Chemical Volcano

1 Empty 25oz. plastic bottle
1 tb Liquid dish detergent
Few drops red food coloring
1 c Vinegar
1 1/2 c Warm water
2 tb Baking soda


Build a mound of dirt around the bottle, keeping the top of the bottle open. Combine the liquid detergent and food coloring in the bottle. Add 1 cup vinegar. Pour in the warm water almost to the top. In a spoon, blend the baking soda with a little tap water to moisten it and then quickly pour into the bottle. Your children will want to try this several times in a row.

Volcano

Make a volcano out of play doh or modeling clay. In the crater put baking soda and perhaps a little red food coloring. To display, pour vinegar in it and watch it erupt!
