Things you need
- Plywood base
- Plastic bottle
- Poster board or wire mesh
- Newspaper strips
- Paint and brushes
- Baking soda, 1 tablespoon
- Liquid dish soap, 1 tablespoon
- Water, 1/4 cup
- Red food colouring, 3 drops
- Vinegar, 1/4 cup
Lay the plywood base down on a flat surface, with the plastic bottle in the centre.
Shape a cone from the wire mesh and secure it to the bottle and the plywood. The opening of the volcano is the mouth of the bottle. Keep it open, to add your liquid solution later.
Mix the paper-mache solution in a pot on the stove, by combining one part flour to five parts water. Boil for approximately 5 minutes: Remove from heat and add 3 teaspoons of salt.
Dip the strips of newspaper into the cooled paper-mache liquid. Place one layer of newspaper strips on the wire mesh to form the volcano exterior. Let the first layer dry for at least 24 hours, before adding two or three more layers.
Paint the volcano in colours that simulate the exterior of a volcano. Add embellishments, like rocks and trees, to create a realistic landscape.
Mix 1 tablespoon baking soda, 1/4 cup warm water, 1 tablespoon liquid dish soap and 3 to 5 drops of red food colouring.
Slowly add 1/4 cup vinegar to the warm mixture to cause the eruption.
Clean any mess created by the eruption, and repeat the eruption process, as needed.
