Experiment with Volcanoes

We did this experiment in the fall when the younger three kids were studying about vocanoes. We used the following supplies:
narrow neck soda bottles
modeling clay and dirt
3-4 tablespoons baking soda
3-4 drops of liquid dish soap
3-4 drops of red food coloring
1/2cup water
1/2 cup vinegar

The kids had alot of fun with this. As you can see from the photos the only thing we should'v done differently is to have maybe doubled the amount of red food coloring. We ended up with pink flowing lava instead of a red.
