The result is a colorful, rubbery egg that you can bounce, and the conclusion is that the vinegar dissolves the eggshell, leaving just the flexible membrane around the raw egg inside.
Step 1. Place a raw egg carefully in a clear jar or cup
Step 2. Pour enough vinegar in the cup to completely submerge the egg.
Step 3. Add in a few generous drops of food coloring and stir gently. To create Rainbow Rubber Eggs make a rubber egg for each color of the rainbow.
Step 4. Observe the eggs each day. The vinegar will dissolve the egg shell over the course of several days. As the shell dissolves it will begin to bubble.
Step 5. After about 3-5 days remove the egg from the vinegar and place it in a bowl of water. Gently rub away the shell to reveal the membrane that lies just below it.
Step 6. Bounce your egg…but not too hard! The egg will now be bouncy and rubbery but it is still raw on the inside. Press it and bounce to test just how rubbery it is but beware, it will still break! Make sure you break at least one to see what the egg looks like inside!
