Egg in vinegar experiment

Interesting, the experiment they send us at my daughter’s school. It is a simple experiment to do with our children and introduce them to the wonderful world of science, although with this we may be conditioning them.

What happens when you put an egg in vinegar

It is also called the bouncing egg experiment


  • 1 egg
  • Vinegar

We have to take a chicken egg and cover it with vinegar. Automatically we will see that bubbles begin to come out of the shell

You can check it after 24 hours although if you wait 48 hours you will get a better result.

After 48 hours, the egg has lost its shell and has increased in size, in addition to creating a rubbery layer, to the point that we can bounce it off the ground without breaking.

Bounce if you are careful, if you do a little the raw bursts, and there remains a layer, a kind of membrane that is what gave it that consistency.

What happens when you put an egg in vinegar?

The eggshell disappears by the reaction of the acetic acid in the vinegar with the calcium carbonate in the eggshell, which forms CO2 bubbles

Osmosis explains the increase in size because the water contained in the vinegar enters the interior of the egg through the semipermeable membrane that covers it.

This is the final result
