Who doesn't have vinegar and baking soda on hand in their house? This is an easy way to kill time if you don't mind a mess! In the past we put the baking soda in a pan or on a plate and used droppers or squirt bottles to create a reaction. They still ask to do it some times when they are bored. Add food coloring to the vinegar and you get even more fun. It fizzes up every time the vinegar hits the baking soda-chemistry 101:)
For a little bit of variety, I taped 2 small cups together and cut a hole in the top. (Think 3rd grade science class volcano) I filled the bottom with baking soda and then gave each kid a squirt bottle of vinegar. When it was done right, it was quite the thrill! Some problems I ran across were: 1. The girls putting the bottle directly into the hole blocked the fizz from coming out. This lead to problem number 2-not getting the vinegar in the cup. Vinegar was all over my table even before the cups had a reaction. The girls loved it though and I had to make a second set of cups. I think they would have done this over and over again. It was really messy and we used a lot of vinegar and baking soda so I had to cut them off at two a piece.

Oh no, it's gone-or squirted on the table:) |
