..lt. depends if there is air inside.... wait.... let me find a easier way to see it bounce

but it does bouce sometimes :D
and if it does, it is extremely cool :D

just found out,, use a fresh egg,, put in vineger more than for 44 hours
than it will surely bounce :DkX/C?^(~

It seems as though the vinegar dissolved the outer shell and created an inner soft shell. FU9Pe2p/Vt@0b
actually, when you see the egg was covered with bubbles, it means the egg is starting to change,.. when you bouce it, make sure you don't poke it too hard, it will break easilyBm] ion

it is extremely cool :D i remember doing similar experiment for my school science fair
B;X$iB7AvM
the egg look like rubber , but my first try wasn't a success :(
but I did it for only 12 hours the first and second time for 24 hours. The acid in the vinegar softens the calcium shell so it can easily be strp away and what remains is the raw egg with some kind of solid shape. You can actually bounce it on a table. (Don't bounce it too high or it will splatter)

DESCRIPTION : A chicken's egg is enclosed by a shell that has a high calcium content. If a raw egg (shell still intact) is placed in a glass of vinegar, a reaction (RXN) takes place. The acetic acid in the vinegar will dissolve the eggshell. The reaction will begin immediately when the egg is placed in the vinegar but will not be complete for two or three days. After two or three days, the egg will survive a drop of four to five inches.
BACKGROUND INFORMATION: This activity can be used to begin a lesson on states of matter. Be sure to completely cover the eggs with vinegar or hard shell will remain on those areas and quickly break the egg when it is dropped. Leave the eggs soaking in the vinegar for at least three days and be very gentle when removing them from the vinegar. \v5l a7iBd}/M

GOAL: The students will observe the chemical reaction between calcium and vinegar. bX1c.w*JE%QE
CONCEPTS: Students will be able to: 7A&a^'@~U(c.r5_+f
Set up and observe the chemical reaction between the calcium in a chicken egg to vinegar.

Test the effects of the chemical reaction by having a bouncing egg contest to see which egg withheld the most bounces.
MATERIALS:
Raw chicken eggs
