How?
The shell of an egg is made of calcium carbonate which is brittle and cracks easily. When the egg is submerged in vinegar, bubbles of carbon dioxide form on the surface of the eggshell. These are produced by the acid of the vinegar reacting with - and dissolving - calcium carbonate in the eggshell. Once the shell has dissolved, the egg is no longer protected from the vinegar and starts to absorb it. The egg is made up of proteins which can be denatured when exposed to heat or acid. The vinegar transforms the outside of the egg into a translucent, rubbery solid which is tough enough to be dropped with out breaking.

How will I test it?
I will draw around an egg at the top of a ramp and it will roll down and hit the ground and it will hopefully bounce . While that is happening I will video in slow motion and have a measuring tape against the wall and see how high it bounces .
