My daughter made these at school and couldn't wait to teach us how.
You need:
a cup
an egg
and plastic wrap
Place the egg in a cup.
Fill the cup, completely covering the egg with vinegar.
It will fizz and bubble a bit.
Leave it for a few days.
The shell will dissolve, but look powdery.
Gently pour out the vinegar and remove your egg.
Under cool running water, gently rub the remaining powdery shell.
It will feel rubbery and might have even grown a little.
You can bounce it and play with it a little, but be careful it isn't rubbery all the way through.
My youngest burst hers shortly after cleaning it off.
The kids loved this!
An Easy Cheap Experiment.
The egg is no longer edible, so don't let the kiddos eat it.
