Membedakan Adjective & Adverb

Posted by Wahyu Putra On 9:48 PM 0 comments

Ada beberapa adverb yang bentuknya sama seperti adjective, seperti hard, fast, dan late. Lantas bagaimanakah cara membedakan jenis kata tersebut dalam kalimat?

Caranya mudah saja. Jika kata tersebut berfungsi menjelaskan nomina, maka kata tersebut berfungsi sebagai adjective. Dan jika kata tersebut menjelaskan verba, maka ia berfungsi sebagai adverb.

Perhatikanlah contoh kalimat di bawah ini!
a. He is a hard worker.
b. He works hard.

Kata hard pada contoh a berfungsi sebagai adjective. Mengapa? Karena ia berfungsi menjelaskan nomina worker. Sedangkan pada contoh b, kata hard berfungsi sebagai adverb yang menjelaskan verba work.

Sekarang bisakah Anda membedakan fungsi kata fast dan late pada contoh-contoh di bawah ini?
a. That is a fast train.
b. Budi runs very fast.

a. Donny is a late sleeper.
b. Tommy always comes late. Selengkapnya...

The elements of India is the most interesting aspect at one side and the fact of Indonesian ethnography. All these facts had invited various experts to study Indonesia in more intensive and extensive effort.

This fact has encouraged the establishment of national museum as the center for Indonesian cultural study.

In the field of history, a big number of collection from ancient Hindu kingdoms, and Chinese ceramic from Hand dynasty ( ca. 300 to 220 AD.

History Of National Museum
On April 24, 1778, a group of Dutch intellectuals stablished a scientific institution under the name Bataviaasch Genotschap van Kunsten en Wetenschappen, (Batavia Society for Arts and Science). This private body had the aim of promoting research in the field of arts and sciences, especially in history, archaeology, ethnography and physics, and publish the various findings.
One of the founders - JCM Radermacher - donated building and a collection of cultural objects and books, which were of great value to start off a museum and library for the society. Due to the growing collections, General Sir Thomas Stamford Raffles built a new premises on Jalan Majapahit No. 3 at the beginning of the 19th century and named it the Literary Society. In the 1862 the Dutch East Indian government decided to build a new museum that would not only serve as an office but also could be used to house, preserve and display the collections.
The Museum was officially opened in 1868 and became known as Gedung Gajah (Elephant House) or Gedung Arca (House of Statues). It was called Gedung Gajah on account of the bronze lephant statue in the front yard donated by King Chulalongkorn from Thailand in 1871. It was also called Gedung Arca because a great variety of statues from different periods are on display in the house.
On February 29, 1950 the Institution became the Lembaga Kebudayaan Indonesia (Indonesian Culture Council) and on September 17, 1962 it was handed over to the Indonesian government and became the Museum Pusat (Central Museum). By decree of the Minister of Education and Culture No. 092/0/1979 of May 28, 1979 it was renamed the Museum Nasional. The Museum Nasional is not only a centre for research and study into the national and cultural heritage, but also functions as an educative, cultural and recreational information centre.
Currently the Musium Nasional houses collections of 109,342 objects under the categories of prehistory, archaeology, ethnography, numismatics-heraldic, geography and historical relics.
In 1994, the museum started with is expansion project. The new building, constructed in the same architectural style as the old, comprises an arena for theatrical performances and more spaces for exhibitions. The building is scheduled for completion this year.

COLLECTION
Prehistory
The Prehistoric Age has long time frame, beginning from the presence of man until the emergence of writing differs in every part of the world. From the discovery of ancient human fossils in Indonesia, it is estimated that man lived here around one million years ago. Writing emerged before the 4th century.
Paleontology, the study of Prehistoric periods, explains the lifestyles of prehistoric civilizations through research into their fossilized remains and the artefacts that they made.
The Neolithic era emerged gradually between 2500 BC and 1500 BC when the vast number of people emigrated from the Asian mainland to the Malaysian peninsula, then to the island of Indonesia by sea. The immigrants built dwellings, planted rice on dry land or in irrigated fields and raised cattle. They formed agrarian village communities. This settled lifestyle enabled men to develop their skills in many areas, thus establishing a specific Neolithic culture, examples of which can be seen in this room.
Treasure Room
The Treasure Rooms are divided into two sections - the Archaeology Room and the Ethnography Room. There are about 2,00 items in the Museum's gold and silver collections, the majority of which were found accidentally rather than on organized digs.
Indonesia has been rich in gold and other precious metals for centuries. Artefacts were made using such processes as casting, soldering, riveting an sewing with gold wire, and were decorated by chiselling, the repousse technique (whereby the design is hammered from the inside of an object), and by adding detailed ornamentation.
Due to the biodegradability of the most materials used by the ancient Indonesian kingdoms, relatively little remains for scholars to base their study of these civilizations upon. As a result, since gold does not deteriorate, these objects are treasured not just for their value and decoration but also for their great historical importance. As well as a high level of culture, the gold items reveal a great deal about the life and rituals of the early kingdoms.
In 1990, farmers found a cache of treasure from java's classical Era ( 5th-15th century ) in Wonoboyo, Klaten, Central Java. These exquisite gold and silver items, collectively weighing more than 35 kg, are believed to have been buried in Lava in the early10th century, perhaps due to a major eruption of Mount Merapi. They comprise the largest find in Indonesia this century and are currently displayed in the showcase in the center of the Archaeology treasure room.
The collection in the Ethnography treasure room comprises objects from the 18th to the early 20th centuries. The artefacts are mostly crafted from 14-24 carat gold and many are adorned with precious stones.
Bronze Collection
Bronze is well-represented in the Museum and the collection, which comprises up to 3,199 pieces, is absolutely spectacular.
The Bronze Age in Indonesia is estimated as having begun around the st century BC, and it drastically changed man's way of life both practically and culturally. Bronze is a mixture of copper and tin, and as it has a low melting point, objects were either produced by forging (heating then beating the bronze) or by wax-casting techniques. Bronze axes, ceremonial items and jewellery were the most popular items made.
With the onset of the Classical Age production and casting processes improved, and techniques such as soldering were introduced. Bronze items became more varied, ranging from statues of Buddha for worship to domestic appliances, and their decoration more ornate. Bronze was also used to replace materials that were easily damaged, so the shape of domestic appliances, for example, did not radically change - a water jar would look the same in bronze as it did in terracotta.
Stone Sculptures
Stone tools and statues have been made by Indonesian civilizations since prehistoric times. The gradual sophistication of these objects and tools used to create them are indicative of cultural progress.The Museum Nasional has a wealth of stone statues in many different forms and sizes, most notably relating to ancestral worship, Hindu gods and goddesses, kings and animals. The statues were usually put in temple alcoves or in the temple's main room (cella), and the majority of them were discovered in Central Java and Sumatra. Volcanic andesite was most commonly used but many of the East Javanese statues made uring the 14th and 15th centuries, were sculpted from sandstone or limestone.As a result of the Hindu-Buddhist influence that was prevalent in Indonesia between the 4th and the 10th centuries, statues created during this period were very similar to those made in East India. Sculptors (silpin). In India had to follow precise rules stated in the Silpasastra book; for example, eyes had to be shaped like lotus (padma) leaves, eyebrows like an archer's bow and arms like an elephants trunk. While these features were copied in Indonesia, the Silpasastra rules were generally not strictly adhered to, and after this period, especially during the Majapahit era (14th and 15th centuries ), statues made throughout the archipelago exuded a more 'Indonesian' style. In the Museum Nasional, Stone Sculpture Collections is included into the Archaeology Section.
Ceramic collection
The ceramics collection differentiates between artefacts originating from countries such as China, Vietnam, Thailand, Myanmar and Japan, and objects made in Indonesia or made in Indonesia or made out of terracotta. This particular collection gives us a good insight into Indonesia's maritime trade over the countries.
Research indicates that the Chinese sailed to India via Indonesia as early as the Western Han period (205 BC to 220 AD) and that firm trade relation were subsequently established.
The islands of Indonesia were the source of many rare commodities and foreign trades were motivated to undertake long and risky sea voyages to get there. Many ships sank before reaching their journey's and, however.
Their non-perishable cargoes, such as ceramics, which would have been used as barter, were washed ashore. Some items were used as common household utensils but fine ceramics were more rare and much sought after. They become cherished heirlooms and were used during the specials ceremonies for birth, circumcision, marriage and death. Occasionally, they were specially commissioned for a private buyer or given as tributes to local dignitaries.
The nucleus of the Museum Nasional's foreign ceramic collection was donated by the Dutch philanthropist and collector, Egbert Willem van Orsoy de Flines, who also became the first ceramics curator of the Museum in 1959.
Although originating in other countries, the ceramics objects in the Museum collection were all found in Indonesia. As well being objects of great beauty, they form an important part of the nation's history. The Museum National is located on the side of Merdeka Square or Lapangan Merdeka and was built in 1862 at that time Dutch colonial administration realized about the great treasure of Indonesian cultural heritages and long history of Indonesia. The biggest surprised for the Western historians was the fact that historical record in Indonesia showing tremendous level of similarities with those in India, India and Asia mainland in general.

TAMAN ISMAIL MARZUKI

Posted by Wahyu Putra On 7:37 AM 0 comments


Taman Ismail Marzuki is Jakarta's showcase in cultural performances. As it is well known Java island including west Java which is called Sunda had strongly influenced by the Hindu tradition in the past. The Hndu tradition, especially initiated by the palaces, were various entertainments developed from local existing dance, drama, and musics with theme of Hindu tradition from India. Ancient Hindu writers in the past also choreographed local theme into the theme of a performances. That is why today both in Jaka and Bali we can watch a drama of wayang puppet shows with a theme both taken from India epic of Ramayana or Mahabharata or local kings in Java or Bali. The artists both in Java and Bali seen to have been free in expressing their emotion and as an art improvisations, taking many events to be included in the chain of their playing. Although it is a traditional performance a modern and actual issues is often appointed into their theme, also it is not into the main theme, or as just for satires Taman Ismail Marzuki organizes almost every night performances from Balinese dances, poetry readings or declamations, traditional musics or gamelan and modern film festivals. The building is located at Jalan Cikini Raya, phone 021 315 4067. Normally their programs are published by the Jakarta Post daily news. Although some groups or small number of people do not like art and consider art is taboo, but the heart of Indonesian people, especially Java could not be avoided form their very basic feeling of life that art can not be separated with all aspect of life which is proved by technologically advanced countries that art has beeen playing a great role in making their creation win over all their competitors. A small number of people do not like art by blaming that art would make the people open to the free sex and other relational affairs is not based on real fact, and if we see the life of such people even they worse in their field of porn, only they try to hide behind some doctrine. As long as history reveals life without art is barren, and make the nature drainaged out of fertilizer and become barren like the sanvannah.

Sinopsis film :



Nim (Abigail Breslin) harus kehilangan ibunya saat seekor ikan paus menyeret ibu Nim ke dasar laut. Ibu Nim adalah seorang ahli biologi laut yang sedang menyelidiki kehidupan ikan paus saat sebuah kapal bernama The Buccaneer berlayar terlalu dekat dengan ikan paus yang kemudian panik dan menyeret ibu Nim ke dasar laut.

Jack (Gerard Butler), ayah Nim, yang merasa kehilangan kemudian mengajak Nim untuk berlayar mengelilingi dunia untuk mencari ibu Nim. Sayangnya mereka berdua malah terdampar di sebuah pulau tak berpenghuni. Mereka berdua kemudian memutuskan tinggal di pulau itu untuk selamanya.

Jack yang juga seorang ahli biologi laut kemudian mulai meneliti kehidupan biota di sekitar pulau itu. Hasil penelitian Jack bahkan sempat dimuat di majalah National Geographic. Selama bertahun-tahun Jack dan Nim tinggal sendirian di pulau itu. Satu-satunya hubungan dengan dunia luar adalah kapal pengangkut barang yang sering singgah dan membawakan mereka beberapa barang keperluan mereka.

Dari kapal inilah Nim kemudian mendapat novel berjudul My Arabian Adventure karya penulis terkenal Alexandra Rover (Jodi Foster) . Dalam novel-novelnya Alexandra selalu berkisah tentang petualangan-petualangan yang menegangkan padahal Alexandra sendiri adalah seorang yang sangat tertutup. Ia bahkan tak pernah keluar dari apartemen tempat ia tinggal.

Suatu ketika Jack berencana untuk mengajak Nim berlayar untuk meneliti kehidupan biota di tengah laut namun Nim merasa keberatan. Jack kemudian berangkat sendiri dan berjanji akan kembali dalam 2 hari. Sayangnya sebuah badai kemudian menghambat kepulangan Jack.

Di saat yang sama, Alexandra yang sedang mengalami kesulitan melanjutkan novelnya menemukan artikel tentang Jack yang tinggal di sebuah pulau terpencil. Alexandra kemudian menghubungi Jack lewat email untuk mencari inspirasi buat novelnya.

Nim yang tinggal sendirian di pulau menunggu ayahnya pulang kemudian membaca email Alexandra dan menjalin hubungan dengan penulis idolanya tersebut. Merasa khawatir dengan keselamatan ayahnya, Nim kemudian minta bantuan Alexandra untuk menyelamatkan ayahnya. Nim mengira bahwa Alexandra adalah seorang pahlawan seperti tokoh-tokoh yang ia gambarkan dalam novelnya.

Film drama petualangan arahan sutradara Jennifer Flackett dan Mark Levin ini adalah hasil adaptasi dari novel karya Wendy Orr dengan judul yang sama. Walaupun jalan cerita sudah dapat ditebak dari awal film, namun sang sutradara cukup cerdik untuk membuat tiap adegan jadi menarik untuk ditonton. Peran Jodie Foster, Gerard Butler, dan Abigail Breslin pun tak dapat diremehkan dalam menghidupkan setiap dialog.

English Version

Movie Synopsis:

Nim (Abigail Breslin) must have lost his mother when a mother whale in tow Nim to the seabed. Nim mother was a marine biologist who is investigating the life of whales when a ship called The Buccaneer sail too close to the whale, which was then panic and dragged the mother Nim to the seabed.

Jack (Gerard Butler), Nim's father, who feel lost and then invite Nim to sail to circumnavigate the world searching for the mother of Nim. Unfortunately, both of them are stranded in an island is not uninhabited. They both then decided to stay on the island forever.

Jack is also a marine biologist and then start researching the life of biota in the vicinity of the island. Results Jack even had time to research published in National Geographic magazine. Over the years Jack and Nim lives alone on the island. The only relationship with the outside world is the transport of goods that often stop by and bring them some of their consumer goods.

Nim's ship and get this novel titled My Arabian Adventure of famous author Alexandra Rover (Jodi Foster). In novel-novelnya Alexandra always about the adventure-the adventure of their own strain on Alexandra is a very closed. He never even out of the apartment where he lived.

A plan for when Jack invites Nim sail to examine the life of biota in the sea but feels Nim objection. Jack and own departure and promised to return in 2 days. Unfortunately the storm and prevent a return Jack.

At the same time, Alexandra is currently experiencing difficulties her novel continue to find articles about Jack living in a remote island. Alexandra then contact Jack via email to find inspiration for the novel.

Nim who lives alone on the island waiting for his father's home and then read the email and Alexandra for a relationship with the author's star. Feel concerned with the safety of his father, Nim and Alexandra ask for help to rescue his father. Nim thinks that Alexandra was a hero like figures that her imagine in her novel.

Adventure landing drama film director Jennifer Flackett and Mark Levin is the result of this adaptation of Wendy Orr novel works with the same title. Although the road may have to guess the story from the beginning of the film, but the canny enough director to make each scene so interesting to watch. The role of Jodie Foster, Gerard Butler, Abigail Breslin, and also can not be fribbled in each of the dialog.

Greenhouse Effect

Posted by Wahyu Putra On 5:10 PM 0 comments

What are greenhouse gases?
Greenhouse gases are a natural part of the atmosphere. It is the increase in the amounts of these gases through human activity that causes global warming. Human activity such as land clearing and burning fossil fuels have increased the concentration of these gases. Humans have had most impact on the enhanced greenhouse effect through increases in the amounts of carbon dioxide, methane and nitrous oxide.

Water vapour
Water vapour is the most important greenhouse gas, but human activity has little direct impact on the amount in the atmosphere.

Carbon dioxide (CO2)
The amount of carbon dioxide in the atmosphere is about 30% higher now than 200 years ago. The main causes of this increase are:

the burning of fossil fuels such as oil, coal and natural gas to create energy to make electricity and to produce fuel for transport, and
the clearing and burning of vegetation.
This gas is the biggest contributor to the enhanced greenhouse effect (about 70%)

Methane (CH4)
The amount of methane in the atmosphere is about 145% higher now than 200 years ago. The main causes of this increase are:

digestive processes of cattle and sheep (ie their burps!)
cultivation of rice
escape of natural gas
decomposing waste in garbage dumps or landfills.
This gas is the second biggest contributor to the enhanced greenhouse effect (about 20%)

Nitrous oxide (N2O)
The amount of nitrous oxide in the atmosphere is about 15% higher now than 200 years ago. The main causes of this increase are:

burning of vegetation
emissions from industries
the effects of agriculture on the soil (using nitrogenous fertilisers)
Halocarbons
These greenhouse gases have been reduced since the phasing out of chlorofluorocarbons (CFCs) to protect the ozone layer. However, other halocarbons effecting the atmosphere include perfluorocarbons (PFCs) emitted during aluminium production.

Fact sheet: Bad gas

How do we make greenhouse gases?
Burning fossil fuels
The burning of fossil fuels for energy (eg. for electricity and fuel for transport) generates the most greenhouse gases. When oil, gas, or coal burns, carbon in the fuel combines with oxygen from the air to form carbon dioxide. Methane is generated from coal mining and some natural gas pipelines.

Removing and burning vegetation
Growing plants absorb carbon dioxide from the air as part of their photosynthesis cycle. Because they absorb carbon dioxide, plants are described as greenhouse gas "sinks". Over many years, forests build up an important store of carbon in trees, soil and fallen leaves. When land is cleared, much of this is rapidly converted back to carbon dioxide by burning or decay.

Farming
Animals, particularly cattle and sheep, produce methane as food breaks down inside them. Some fertilisers release nitrous oxide. Rice production in paddy fields generates methane under water.

Waste breakdown
When organic material such as food scraps, garden wastes and paper are dumped in landfills, their decay creates carbon dioxide and methane. Sewage and wastewater treatment plants also release these gases as they break down wastes.

Industry
Many industrial processes create greenhouse gases. For example, cement and aluminium production involves chemical reactions that produce a variety of greenhouse gases.

BUT...we get help from the oceans and forests
The ocean absorbs carbon dioxide from the atmosphere. It also acts as a moderating influence on temperature ranges.

Forests also absorb carbon dioxide. Green plants use the energy of the sun and carbon dioxide from the air for photosynthesis; they create carbohydrates - the basis of the food chain on which almost all living things depend. Thus forests are a major store or bank of carbon, holding it in their trunks, roots, stems and leaves.

Do Not Open Bottle - Soda Prank It's the ultimate prank.

Do Not Open Bottle - Soda Prank

It's the ultimate prank using the simplest of props... a plastic soda bottle filled with water. Even though the words, "DO NOT OPEN" are printed on the bottle, people just can't resist the temptation. Watch out, the fun is just beginning.

Materials

  • Two plastic soda bottles (1-liter size works well)
  • Cap
  • Large nail
  • Sharpie pen
  • Thumb tack

Hey, if you're a kid who is trying to do this experiment, get an adult to help you poke the holes in the bottle. You don't want to hurt YOUR hand!

Experiment

The Leak-Proof Bottle
  1. Use the nail to poke a hole on the side of the bottle close to the bottom.
  2. Cover the hole with your finger while you fill the bottle with water all the way to the top. Screw on the cap.
  3. Slowly take your finger away from the hole. Are you ready for the water to come rushing out. Hey, there's no leak?
  4. Unscrew the cap and watch what happens. Okay, now it's time to stand back!

The "Do Not Open" Bottle Trick

  1. Start with a new plastic soda bottle (don't use the one from the previous experiment). Use the permanent marker to write DO NOT OPEN! in fat letters on the bottom half of the bottle.
  2. Use a sharp push pin (thumb tack) and carefully poke tiny holes through the bottle at the bottom of the letters (the letters will help hide the holes).
  3. Place the bottle in a deep sink or pan and fill it with water. The tricky part is that the water will leak out of the holes as you're filling the bottle. Keep the water running as you screw on the cap. Don't squeeze the bottle or it will start leaking before you're ready.
  4. Set the bottle on the kitchen counter (word-side out) where someone can see it as they pass by. Stay close enough to watch what happens. Eventually, someone is bound to ask about the bottle. Play dumb with, œI dunno when they ask about it. Let them unscrew the cap and you'll witness science in action!

How does it work?

Think about why the bottle spews water when the cap is loosened. It's kind of a tag team combo between gravity and air pressure. Gravity is pushing downward on the water whether the lid's on the bottle or not. Air pressure can't do anything until it somehow gets into the bottle. When the lid is on, air pressure can't get into the bottle to push on the surface of the water. It does, however, push against the outside of the bottle on all sides. Since the outside atmospheric pressure is greater than the force of gravity, most of the water stays in the bottle. When the lid is uncapped, though, the outside atmospheric pressure (14.7 pounds per square inch at sea level) and the force of gravity push down on the water at the same time. The water shoots out and the nosy person gets a scientific (but well-deserved) soaking.

Floating Balls & Flying Toilet Paper Amuse the neighbors for hours.

Floating Balls & Flying Toilet Paper

Amuse the neighbors for hours as you make objects floating in mid-air. Believe it or not, the secret to this mystery of levitation is right in front of your nose.

Materials

  • Hair dryer
  • An empty toilet paper tube
  • A ping-pong ball/ balloon/beach ball
  • A roll of toilet paper
  • A leaf blower!
Experiments
  1. Set the hair dryer to cool, switch it on, and point it at the ceiling.
  2. Carefully put the ping-pong ball in the stream of air. Hold the hair dryer very steady and watch as the ping-pong ball floats in the stream of air.
  3. Carefully move the hairdryer from left to right and watch how the ball moves as well, staying in the stream of air.
  4. Try floating other lightweight objects in the air stream at the same time! With the hair dryer on, place an inflated balloon over your levitating ping-pong ball. You might want to place a penny in the balloon before you blow it up to give it some added weight.
  5. Try to float two or more balls in the same air stream. How many can you float at once? How do they behave when there is more than one?
  6. Need more power? Try using a leaf blower in place of the hair dryer. Now you can float larger objects like beach balls.

Flying Toilet Paper! Just hold a roll of toilet paper in the stream of air and watch the paper take off! Be sure to hold the toilet paper roll on a long stick (piece of dowel) in order for it to spin fast and unroll the paper. Always conclude this demo with a thanks to Bernoulli (see below if you don't get it).

How does it work?

The floating ping-pong ball is a wonderful example of Bernoulli's Principle, the same principle that allows heavier-than-air objects like airplanes to fly. Bernoulli, an 18th century Swiss mathematician, discovered something quite unusual about moving air. He found that the faster air flows over the surface of something, the less the air pushes on that surface (and so the lower its pressure). The air from the hair dryer flows around the outside of the ball and if you position the ball carefully, the air flows evenly around each side. Gravity pulls the ball downwards while the pressure below the ball from the moving air forces it upwards. This means that all the forces acting on the ball are balanced and the ball hovers in mid air. Airplanes can fly because of this principle. Air rushing over the tops of airplane wings exerts less pressure than air from under the wings. So the relatively greater air pressure beneath the wings supplies the upward force, or lift, that enables airplanes to fly. You can make the ball follow the stream of air as you move the hairdryer because Bernoulli's principle says that the fast moving air around the sides of the ball is at a lower pressure than the surrounding stationary air. If the ball tries to leave the stream of air, the still, higher pressure air will push it back in - so the ball will float in the flow no matter how you move. When you place the empty toilet paper tube into the air stream, the air is funneled into a smaller area, making air move even faster. The pressure in the tube becomes even lower than that of the air surrounding the ball, and the ball is pushed up into the tube.

The Egg in the Bottle Trick How to get the hard-boiled egg into the milk bottle.

The Egg in the Bottle Trick

Here's a classic science experiment that is more than a hundred years old and is guaranteed to fool your friends. The original demonstration used a hard-boiled egg and a milk bottle.


WARNING: This experiment requires the help of an adult partner. Don't just pick any adult... try to find a smart one!

Materials

You'll need:
- A wide mouth juice bottle
- Hardboiled eggs
- Several strips of paper (2X6 inches)
- Matches
- A few balloons
- Water.

The classic version of this experiment used a glass milk bottle. If you can get your hands on one of these bottle, you'll be in science heaven!

Experiment
The object of the challenge was to somehow get the whole egg into the bottle without harming the egg. Since old milk bottles are hard to come by, here’s a modern day version of the same experiment only this time we’re using a juice bottle and a water balloon! Your job is to get the balloon in the bottle, but don’t break the balloon, or you’ll be all wet.
  1. Carefully fill the balloon with water, so the balloon is about the size of a tennis ball, and tie if off. Make several balloons just in case the first one breaks!
  2. Rinse out the bottle to remove any leftover, sticky, slimy stuff that might be in the bottom. Before going any further, make sure that the water balloon is slightly larger than the mouth of the bottle.
  3. Here’s the challenge: Your job is to find a way to get the balloon into the bottle… without breaking it. How are you going to do it? It’s important that you take a minute to test out some of your ideas before jumping ahead to read our solution. Keep trying!

Once you get the balloon in the bottle, how are you going to get it back out? Here's our answer!

  1. Start by smearing some water around the mouth of the bottle.
  2. Have the adult light a match and set the strip of paper on fire. Quickly put the burning strip into the bottle. Be careful not to accidentally burn your fingers.
  3. Immediately cover the mouth of the bottle with the balloon. In just seconds, the balloon will start to wiggle around on the top of the bottle, the fire will go out, and some invisible force will literally “push” the balloon into the bottle. That’s amazing!

Try it with an egg!

Just repeat the steps above substituting a hardboiled egg for the water balloon. The trick here is to find an egg that is just a little bigger than the mouth of the bottle - I prefer medium size eggs. The other little secret is to grease the mouth of the bottle with a vegetable oil so the egg slides right in!

How does it work?

The burning piece of paper heats the molecules of air in the bottle and causes the molecules to move far away from each other. Some of the heated molecules actually escape out past the water balloon that is resting on the mouth of the bottle (that’s why the balloon wiggles on top of the bottle). When the flame goes out, the molecules of air in the bottle cool down and move closer together. This is what scientists refer to as a “partial vacuum “. Normally the air outside the bottle would come rushing in to fill the bottle. However, that darn water balloon is in the way! The “push” or pressure of the air molecules outside the bottle is so great that it literally pushes the balloon into the bottle.

Remember this: When molecules of air heat up, they move far away from each other and take up more space. When molecules of air cool down, they move closer together and take up less space. Now, the challenge is to get the balloon out of the bottle. Use what you have learned about air and air pressure to come up with a way to get the balloon back out. Hint: Try sneaking a straw along side the balloon when you pull it out. If the outside air can get inside the bottle, the water balloon will come out!
