    1. Shap cardboard into a broad cone, forming a "crater" at the top with a small plastic cup. Cover the cone with plaster of Paris, being careful to keep plaster from the crater. Allow volcano to dry and paint as desired.

    2. In a plastic cup, mix 1/4 cup vinegar with a few drops each of dishwashing soap, water, and red food coloring.

    3. Add 1 teaspoon of baking soda to a small empty plastic cup placed inside the volcano crater.

    4. Wearing goggles, quickly pour vinegar mixture into the cup holding the baking soda mixture. Stand back and watch the reaction!
