My hypothesis for the question “Will an egg bounce if you soak it in
vinegar?” is that the egg will bounce if you soak it in vinegar because
the acetic acid in the vinegar will break down the shell of the egg and
will eventually disintegrate the shell. The membrane of the egg will
become the outside layer and the membrane will bounce from 2 to 3
feet because the membrane has something called keratin which makes
it tough. Keratin allows the membrane to bounce.
ALL THIS CAUSES THE EGG TO BOUNCE :
My research showed that the egg will bounce because of the
substance acetic acid in vinegar
Calcium carbonate is what makes the shell of an egg hard and what
makes the shell crack easily
When the acetic acid of the vinegar comes in contact with the
calcium carbonate the acetic acid disintegrates the calcium carbonate
This leaves the membrane of the egg
 The membrane contains something called keratin which
allows the egg to be tough and bounce
THESE ARE THE MATERIALS NEED TO COMPLETE THE EXPERIMENT:
 1 hard-boiled egg
 1 raw egg
 2 cups of white vinegar
 2 clear jars or glasses
 1 spoon big enough to pick an egg up
 A ruler to see how high the egg will bounce

Get the materials you need
Cook an egg in boiling water to make it hard-boiled
Get a raw egg
Pour white vinegar into 2 glasses big enough to hold an egg
Put a hard-boiled egg a glass filled with white vinegar
Put a raw egg in a glass filled with white vinegar
Leave the egg in the vinegar for 24 to 48 hours
Take the egg out of the cup of vinegar
Observe the egg and see if the eggs shell has dissolved
Drop the egg from 2 to 3 feet
Measure how high the egg bounced
Record your observations

My conclusion is that if you soak an egg in vinegar for a few days it
will bounce. This means my hypothesis was right because my
hypothesis said that the egg would bounce because of the acetic acid in
vinegar that dissolves the shell. Though I was right in saying that the
egg would bounce, I was wrong and right in saying that it would
bounce from 60 to 90 centimeters. The raw egg exploded when I
dropped it from 50 centimeters, but the hard-boiled egg bounced from
90 centimeters. I hope this experiment showed that an egg will bounce
if you soak it in vinegar.
