How to Make a Model Volcano?

The model volcano is one of the oldest science models you can make. You’re limited only by how decorative you want the outside of the volcano to look. The inside of the volcano should be hollow and have enough space a container to hold about two spoonfuls of baking soda and dish washing liquid. When you’re ready, pour in about an ounce of vinegar to watch it erupt! Mix in some red food coloring for a nice color effect.
