Revolt your mates with this Little Eureka which only requires one fresh egg and some brown or white vinegar.
Pop the egg into a bowl and cover it in vinegar.

Stand by for the smell!
The egg will start to fizz, and the shell gradually dissolves in the vinegar.
Eventually, the shell goes very squidgy.

Eww!
The vinegar goes right into the egg, and it becomes so squidgy that it can be bounced like a bouncy ball!
Gross but incredible.

And inedible - don't eat it!
