Bottle Volcano Experiment

Make a volcano from a bottle in this cool experiment!

Age Group: Elementary School (with adult supervision)

Topics: Chemical Reactions

Difficulty: Easy to perform and see results


  • Dish soap: 1 tablespoon

  • Cold Water: 0.5 cups

  • Vinegar: 2 cups

  • Food coloring: 2 drops

  • Baking soda: ½ cup

  • An empty bottle narrow neck


1. Add and mix together 1 tablespoon of dish soap, 1/2 cup of cold water, 1-2 drops of food coloring, and 2 cups of vinegar into the empty bottle

2. In a separate cup, mix together 1/2 cup of baking soda and 1/2 cup of water. Mix it until it is consistent throughout and there are no clumps.

3. Move to an outdoor location for this part to avoid any messes. Now pour your baking soda mixture into the bottle.

4. Watch your volcano explode!

How it works

When we mix together all the ingredients, the Baking Soda (Sodium Bicarbonate) reacts with Vinegar (Acetic acid)to produce Sodium Acetate, Water, and Carbon Dioxide.

This is the chemical reaction:

When the carbon dioxide gas is produced, it tries to escape from the mixture out of the bottle. This causes bubbling to occur. This bubbling agitates the dish soap, making the bubbling eruption occur.
