Bouncing Egg
Here is a fun project you can do at home -- bouncing an egg! It is pretty simple and takes a day or two, but it's worth your time.
Put the Egg in Vinegar
First, you want to put the raw egg into vinegar. After a few days, it will have NO white of the shell on it. This means it is ready to bounce. Take it out of the vinegar.
Bouncing the Egg
To bounce it, you simply drop it from a short height (2 inches or so), then increase the height as you keep doing it.
