Baking Soda & Vinegar Chemical Volcano

By Anne Marie Helmenstine, Ph.D., About.com Guide

You can cause an eruption without making a 'volcano', but it's easy to model a cinder cone. Start by making dough:

1. Mix together 3 cups flour, 1 cup salt, 1 cup water and 2 tablespoons of cooking oil.
2. Either work the dough with your hands or stir it with a spoon until the mixture is smooth.
3. If you like, you can add a few drops of food coloring to the dough to make it volcano-colored.
