Wizard" television show, which premiered in I like to use this demonstration at the beginning of my unit on heat and pressure to introduce the concept of air pressure. It is a great and inexpensive demonstration to illustrate the way temperature affects pressure and students are absolutely fascinated by the results. Many of us who were in school in the 60s and 70s will immediately remember the phrase, "Why is it so? Miller delighted thousands of budding scientists and their parents with a series of television programs on physics.

Sucking egg experiment

Lift the egg off the bottle, drop the paper inside with the flame down, and quickly replace the egg. Find a bottle with a long, narrow neck and set it on the Sucking egg experiment. This means that the air pressure inside the bottle will reduce allowing the air pressure outside to push the egg into the bottle. Sucking an egg through a bottle is done by changing the atmospheric pressure in the bottle by adding heat. She holds a Bachelor of Arts in communications and print journalism from California State University. As the air then cools down again it starts to Sucking egg experiment, this pulls the egg down and forms a good seal. Is it possible for the laws of physics to change in time? What happens?

You could do the experriment with fewer matches. I'm very very happy. What You Need: Eggs Saucepan and stove Wide-mouth glass drink bottle such as a Starbucks Frappuccino bottle - Sucking egg experiment mouth needs to be a little smaller than the egg. Thank you to Proteins expriment made of long chains of amino acids, but in an egg the chains are clumped tightly together in individual spheres. Whether it's over eager young scientists year after year, or rigorous requirements that come once-in-a Sucking egg experiment. Use a paper towel to coat the inside edge of the bottle mouth with a little bit of vegetable oil for lubrication.

  • Introduction Have you ever been helping in the kitchen and found yourself with a recipe that calls for egg whites?
  • The Egg in a Bottle experiment illustrates the effects of air pressure.
  • This experiment shows how differences in pressure create a vacuum-- with mind-boggling results.
  • It may seem like an impossible feat to get an egg inside of a milk bottle, but with a little scientific understanding and some common household items, it is totally possible!
  • Learn about the relation of temperature and pressure as you watch an egg get sucked into a bottle.

Soaking an egg in vinegar and then sucking it through a bottle is like two experiments in one. By soaking the egg in vinegar, the shell — which is made up of calcium carbonate — gets eaten away, leaving the membrane of the egg intact. Sucking an egg through a bottle is done by changing the atmospheric pressure in the bottle by adding heat. Both experiments can be done with raw or hard-boiled eggs. Place the egg into a bowl filled with white vinegar.

Allow the vinegar to cover the egg completely and let it sit, undisturbed, for 24 hours. Drain the vinegar. Soak the egg again in new vinegar for another 24 to 48 hours. You want to end up with an egg that is soft, with no shell left. The membrane of the egg will be intact leaving you with a see-through raw egg or a more rubbery hard-boiled egg. Gently rinse the egg with water and allow it to dry. Light a piece of paper or other flammable material with a match or lighter and put it into the bottle quickly.

If you are using a raw egg, be sure to carefully place the egg onto the bottle and be prepared in case it breaks. Christina Martinez has been writing professionally since She holds a Bachelor of Arts in communications and print journalism from California State University.

Take your egg from Step 2 outside to conduct the bottle experiment. Grease the opening of the bottle with a little vegetable oil. Place the egg on top of the bottle and wait for the egg to be sucked through the bottle. About the Author.

Full reference:. This increases the pressure inside the bottle so that the egg can escape. Hold Bottle 2 over the plate with the opening of the bottle facing downward. It can be helpful to tap the egg on the counter to crack the shell so that it is easier to peel. This trick works because when the matches burn, they heat up the air inside the bottle and release steam water as a part of the combustion reaction.

Most of the changes in a particular place's weather are governed by air pressure. In this experiment, you will learn more about air pressure and its behaviour by putting an egg into a bottle and taking it out again without destroying the egg.

For the Egg in a Bottle experiment, you will need the following items:. Get an egg and hard boil it. Make sure that you cool it down before proceeding. Seek help from an adult or at least their supervision while you cook the egg. After setting it aside to cool down, start peeling off its shell.

Now, take the newspaper and tear one page into strips. It is recommended that you perform the following procedure with the supervision of an adult. Insert the strips of newspaper into the bottle, and take your match to light it.

Drop the lit matchsticks into the bottle so it burns the newspaper strips inside. Quickly take the egg and place it in front of the opening of the bottle. Watch what happens! And to take it out? Put your mouth on the bottle opening and blow air into the mouth of the bottle. Be aware that the egg will pop right out of the bottle again when you do this! Amazing huh?

You just managed to insert a hard-boiled egg into a bottle with a narrower opening and you were even able to take it back out without destroying it! How is this possible? Air pressure is the answer! The experiment just showed you the behaviour of air pressure.

In our Egg in a Bottle experiment, after setting the newspapers on fire with the use of the lit matchsticks, the oxygen in the bottle is used up. When you placed the egg in front of the opening, the air inside creates a vacuum sucking the egg into the bottle. The burning newspapers heats the air trapped inside the bottle causing it to expand. After a short while, the fire inside the bottle dies, thus causing the air inside to cool down then resulting in a lower pressure inside the bottle.

The egg is forced into the bottle because there is a lower pressure inside, and a greater pressure outside the bottle. Now, after turning the bottle upside down and blowing air into the bottle, the air pressure inside the bottle increases then pushing the egg back out its opening while at the same time keeping it intact!

That is it. The consistency has changed from runny egg white to a soft solid! So how does this squishy-but-solid egg get mysteriously pushed inside the bottle? The answer is all about air pressure.

When you first set the egg on the bottle, the air pressure inside the bottle matched the air pressure outside, so nothing happened. When you dropped the burning paper into the bottle, it caused the air inside to heat up and expand rapidly. That expanding air pushed the egg aside and escaped from the bottle; that's why you saw the egg vibrating.

When the fire consumed all the oxygen inside the bottle, the flame went out and the remaining air in the bottle cooled down. Cool air takes up less space, exerting less pressure inside the bottle. The egg acted as a seal to prevent outside air from getting in to fill the extra space. The result was an unbalanced force—the force of the air pushing on the egg from outside the bottle was greater than the force of the air pushing up on it from inside the bottle.

Voila - the egg was pushed into the bottle! How do you get the egg out again? You need to increase the pressure inside the bottle. Turn the bottle upside down and tilt it until the small end of the egg is sitting in the mouth. Now put your mouth close to the bottle and blow, forcing more air into the bottle and raising the pressure inside. When you take your mouth away, the egg should pop out - just be careful it doesn't hit you in the face!

Put the jar in a tray the jar may crack in the next stage so this will catch any spillage of hot water. When you add the match or the hot water you cause the air inside to expand, this will push the egg up slightly and some air will escape.

As the air then cools down again it starts to shrink, this pulls the egg down and forms a good seal. This means that the air pressure inside the bottle will reduce allowing the air pressure outside to push the egg into the bottle. And because a boiled egg is very rubbery and flexible you can get it into a bottle that has a neck far smaller than you would expect. When you add the match the air heats up and expands. Though there is always the simple mash it up and take it out in pieces option, there is a much more elegant and scientific strategy.

Hold the bottle upside down so the egg falls over the neck, then blow into the bottle as hard as you can, the egg should then be pushed out by the higher pressure air inside the bottle, so you can still eat it for your tea. Blow air into the bottle around the egg. This raises the pressure inside the bottle which pushes the egg out again. Skip to main content. Play Download. Ingredients A hard boiled Egg A bottle with a neck slightly narrower than the egg Some boiling hot water or a lit match A tray Some oil to lubricate the outer surface of the egg.

Instructions Peel the egg and lightly oil the outside to lubricate it Then either: Light a match and put it in the jar Put the jar in a tray the jar may crack in the next stage so this will catch any spillage of hot water Add a little boiling water to the jar Then quickly put the egg on the top and wait.

Result You should find that the egg is slowly sucked into the bottle. Explanation When you add the match or the hot water you cause the air inside to expand, this will push the egg up slightly and some air will escape. When you add the match the air heats up and expands When the match goes out the air shrinks reducing the pressure inside the bottle.
