How to suck an egg throgh a botlle

A quick, easy tutorial on how to get an egg through a bottleneck and into a bottle--a classic, wow your friends science experiment. Bottom line, science is cool. It's got the wow factor of magic and the additional bonus in that it helps us explore the world around us.

An easy and funny experiment for kids to get an egg into a bottle through the neck. The law of physics that we will use for this experiment is the expansion and contraction of air. When placed inside the bottle, the ignited paper heats the air.

The egg in a bottle demonstration is an easy chemistry or physics demonstration you can do at home or in the lab. You set an egg on top of a bottle as pictured. Air pushes the egg into the bottle.

For this experiment, you are demonstrating how air pressure works by sucking a hard-boiled egg into a bottle. First, you will boil water. I put 4 cups of water in a Pyrex measuring cup and microwaved it for about 5 minutes.

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.

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.

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.

At what temperature setting should you first boil an egg in order to get it inside a bottle? Not exactly! Pick another answer!

What happens? The lit matches heat the air inside the bottle. When air is heated it expands and takes up more room.

Astound your kids and show them nature's laws in action with this cool learning activity. A boiled egg may seem unassuming, but under the right conditions, it can be a powerful thing. In this classic demonstration of how a vacuum must be filled, the egg withstands a mighty force of nature at least for a little whileuntil the experiment's surprising -- and kid-pleasing!
