Experiment with egg and vinegar

Did you know that if you put an egg in vinegar for two days, the shell will dissolve and the egg will become elastic. Under the influence of vinegar, calcium, which makes up the shell, dissolves and disappears in the form of gas bubbles. It turns out a funny egg that looks like jelly. If you put an experiment on a boiled egg, then it will become elastic, like a rubber ball.

Pour table vinegar (9%) into a transparent glass and drop a chicken egg into it. Carbon dioxide immediately begins to be released from the surface of the egg.

The shell of bird eggs consists of 90 percent calcium carbonate. Therefore, when interacting with acid, it begins to disintegrate, releasing CO2.

After 12 — 15 hours, we look at what happened. The calcium from the egg's surface has dissolved. Only the film between the shell and the egg remained intact.

Remove the egg from the vinegar and rinse with running water.

The egg has slightly increased in size, as it has been saturated with vinegar.

There is no shell and you can play with an egg as a ball. The film is very thin, and therefore may break if handled carelessly.

Now this rubber egg can be enlightened through and through.

Attention: it is forbidden to eat such an egg!
