Rubber Egg
Materials: clear jar with lid
vinegar
raw egg in its shell
1. Put a raw egg in a jar and then cover it with vinegar. Screw on the lid and set it aside for 3-5 days.
2. Observe the egg each day and describe what is happening to it.
3. After 3-5 days, the eggshell should be almost invisible. Remove the egg, rinse it off, and hold it up to the light. How does the shell feel? Hold the egg several inches from the table and drop it. Does it break?
*I can't wait to do some of these with K.J. and Kalina when they visit next week.
