Quick and Easy Way to Make an Erupting Volcano


6 cups flour

2 cups salt

4 tablespoons cooking oil

warm water

plastic soda bottle

dishwashing detergent

food coloring


baking dish or another pan

2 T baking soda


How to Make the Chemical Volcano

First, make the ‘cone’ of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).

Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape. Don’t cover the hole or drop dough into it.

Fill the bottle most of the way full with warm water and a bit of red food color (can be done before sculpting if you don’t take so long that the water gets cold).

Add 6 drops of detergent to the bottle contents. The detergent helps trap the bubbles produced by the reaction so you get better lava.

Add 2 tablespoons baking soda to the liquid.

Slowly pour vinegar into the bottle. Watch out – eruption time!
