My Shell-less Egg

And It Bounces

The Trick : Soak Normal Egg In Vinegar

What happened:
The shell disappeared! The egg became bouncy. But we bounced it too hard. Splat! That was the end of it.


How come:
The vinegar (acid) dissolves the shell which is made of calcium carbonate. There are lots of bubbles on the egg because carbon dioxide is released. The membrane of the egg holds the contents in but when we bounced it too hard, the membrane broke. Mum says if you want a hardier bouncy shell-less egg, use a hard boiled egg.

(Em, how would the hen feel about a shell-less egg?)
