  * try doing several of these side by side - several jars

Words to look up

The reaction of the eggshell and the vinegar is an acid-base reaction. Calcium carbonate, (a base), that makes up the shell reacts with the vinegar (acid) to make carbon dioxide.
The vinegar breaks apart the solid calcium carbonate crystals which the eggshell is made of, into their calcium and carbonate parts. The calcium ions (ions are atoms that are missing electrons) float free, and the carbonate makes carbon dioxide - this is where you see those bubbles.
