Bounce an egg

Bouncing an egg with no magic, however science!
           

 Materials:
1. Raw egg
2. Clear glass
3. Vinegar
4. Spoon
5. Plate or shallow bowl.

Step 1:
Gently place a raw egg in a clear glass.

Step 2:
Fill the glass to about 1 inch (2.54 cm) above the egg with vinegar.

Step 3:
Watch what happens as the egg is in the vinegar. What do you observe? The bubbles point out a chemical response is taking place. It will take about two days to rubberize your egg, so find a vicinity where the glass can remain undisturbed for that long.

Step 4:
Remove the Rubber Egg from the vinegar with a spoon. Rinse it off in the sink and place it on a plate or in a shallow bowl.

Step 5:
Push your fingertip into it. What does it feel like? You can drop it
from few inches onto the plate and watch it strive to bounce. You should
thoroughly wash your arms when performed seeing that Rubber Eggs (and raw eggs)
can dangle onto some nasty germs.

The Science Behind It :

The calcium of the egg reacts with the acetic acid (vinegar) to dissolve the shell. The
white part of the egg becomes the new outside. The membrane of the egg
holds the inner together. The membrane is bendy and will break if treated
too roughly.
