Raw to Rubber Eggs
Put a raw egg in a glass.
Fill the glass with vinegar and let it sit for a day and night.
Remove the egg and go experiment dropping it in the sink.
When vinegar, which is acidic
, combines with the calcium carbonate
of the shell, it breaks it down. A chemical reaction has taken place! Did you observe any bubbles? Carbon dioxide
, which is a gas, is released during this process.
Try leaving this rubbery egg out for another day. What's happened now?
