How to make it
Raw egg can carry salmonella, so wash hands after touching it and throw it out when you're done.
1Drop in the egg
Set a raw egg gently in the glass. Pour in vinegar until it's covered.
2Watch the bubbles
Look close. Tiny bubbles form on the shell right away.
3Change the vinegar
After 1 day, scoop the egg out with a spoon. Pour in fresh vinegar and put the egg back.
4Wait 1 to 2 more days
Leave it until no shell is left. It'll look bigger and a bit see-through.
5Rinse and feel
Rinse it gently. Feel the rubbery skin. Bounce it 1 in above a plate and see if it holds.
6Talk about why
Eggshell is made of calcium carbonate. Vinegar's acid breaks it apart, and that makes the carbon dioxide bubbles. The thin skin under the shell is left behind.
Edie's tipShine a flashlight through the egg in a dark room. You can see the yolk inside.
