How to make an erupting Volcano Soda in the classroom or at home.                 (Adult supervision is recommended.)

Ingredients: 

Cardboard, Three 4-oz. plastic cups, 1 teaspoon ARM & HAMMER™ Baking Soda, Plaster of Paris, ¼ cup vinegar, Liquid dish soap, Water, Red food coloring.

Directions:

1. On a baking sheet (or other easily cleaned surface), shape cardboard into a broad cone shape using a cup to form a “crater” on top of the volcano.

2. Use Plaster of Paris over the cone to form the volcano (do not get plaster into the crater). Allow to dry completely.

3. Paint or decorate volcano as desired.

4. Mix vinegar, dish soap, a few drops of water, and a few drops of red food coloring in a plastic cup.

5. Add 1 teaspoon ARM & HAMMER Baking Soda into a small, empty plastic cup. Place this cup into the volcano crater.

6. Quickly pour the vinegar mixture into the ARM & HAMMER Baking Soda cup in the crater. Enjoy the “lava” as the volcano erupts.
