What would happen if you put an egg in corn syrup?

Bigger molecules—like the sugar molecules in the corn syrup—don't pass through the membrane. When you put a naked egg in corn syrup, you are creating a situation where the egg membrane separates two solutions with different concentrations of water. The egg white is about 90% water; corn syrup is about 25% water.

Accordingly, what happens when you put an egg in vinegar then in corn syrup?

Water moves through the membrane easily. Bigger molecules, like the sugar molecules in the corn syrup, do not pass through the membrane. You may have noticed that the egg expanded in the initial vinegar solution when you dissolved the shell. When a naked egg is placed in the corn syrup the egg will shrink.

What happens when you put an egg in vinegar for 3 days?

If you soak this egg shell in vinegar (which is about 4% acetic acid), you start a chemical reaction that dissolves the calcium carbonate shell. The acetic acid reacts with the calcium carbonate in the egg shell and releases carbon dioxide gas that you see as bubbles on the shell.

How do you shrink an egg?

Experiment
  1. Fill multiple glasses with vinegar.
  2. Allow eggs to soak in vinegar for 24 hours. You will be left with the membrane, but no shell.
  3. Fill one glass with Karo corn syrup.
  4. Fill another glass with water and place one “naked” egg inside each glass.
  5. Pull the eggs out of the glasses and observe what has happened.
