This is a very simple and common experiment. Some people do it with carbonated beverages, we used the good ol' baking soda and vinegar method (we go though a LOT of these two items in a month...)
Could not be any simpler, but if you put music in the background and see these raisins dance, the kids will have a blast!
- baking soda
- CLEAR TALL glass
First, fill up the glass with water, about half way. Remember, when you add the vinegar to the baking soda it reacts and it goes all the way to the top!!
Add baking soda, about 1 tablespoon
Add the raisins
Stir. Add vinegar by teaspoonfuls.
Watch it react!
Put some music and watch them dance!
