3HYPOTHESISMy 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.
4RESEARCH ALL THIS CAUSES THE EGG TO BOUNCE : My research showed that the egg will bounce because of the substance acetic acid in vinegarCalcium carbonate is what makes the shell of an egg hard and what makes the shell crack easilyWhen the acetic acid of the vinegar comes in contact with the calcium carbonate the acetic acid disintegrates the calcium carbonateThis leaves the membrane of the eggThe membrane contains something called keratin which allows the egg to be tough and bounce
5MATERIALS THESE ARE THE MATERIALS NEED TO COMPLETE THE EXPERIMENT: 1 hard-boiled egg1 raw egg2 cups of white vinegar2 clear jars or glasses1 spoon big enough to pick an egg upA ruler to see how high the egg will bounce
6PROCEDURE The procedure for my experiment is: Get the materials you needCook an egg in boiling water to make it hard-boiledGet a raw eggPour white vinegar into 2 glasses big enough to hold an eggPut a hard-boiled egg a glass filled with white vinegarPut a raw egg in a glass filled with white vinegarLeave the egg in the vinegar for 24 to 48 hoursTake the egg out of the cup of vinegarObserve the egg and see if the eggs shell has dissolvedDrop the egg from 2 to 3 feetMeasure how high the egg bouncedRecord your observations

9CONCLUSIONMy 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.
