How to Make an Egg Bounce

The wonderful egg provides healthy protein and a good breakfast. But it's also useful in science experiments. Ask anyone if an egg bounces, and you're certain to receive some odd looks. Amaze your friends by following these steps to make an egg bounce.

Things You'll Need

• Egg
• Container: jar, glass, bowl
• White vinegar

Instructions

1. Place an egg in your container. Pour white vinegar over it.

2. Leave the vinegar covered egg alone for a week. You should notice some fizzing as the vinegar interacts with the egg.

3. Remove the egg from the vinegar. Notice that the egg's shell has disappeared. Eggshells are made up of calcium carbonate, which dissolves in vinegar. The egg should feel rubbery.

4. Drop your egg from about a foot high. You should notice that it bounces.

5. Try dropping the egg from slightly higher points. Watch out! Your egg may break when dropped from more than a few feet.

Tips & Warnings

• If you want to speed the experiment, hard boil the eggs first. Once eggs are cool, soak them in vinegar for 48-72 hours until the shell dissolves. Then soak the egg in water overnight.

• Take the egg from the vinegar into a dark room. Shine a flashlight on it to see the light bounce off the egg.

• Don't eat your experiment! Even if you're tempted, the egg is no longer edible and would make you sick.
