Making a volcano in a bottle is a great (and fun) way to teach kids about chemical reactions and also teach them about volcanos.
Here’s what you will need:
- an old soda bottle or water bottle (I used an old wine bottle)
- 1 Table spoon of baking soda
- a drop of food coloring
- 1/4 cup vinegar
- water
Place your bottle in the kitchen sink (or in your yard). Make sure the bottle is filled about 2/3 the way with water.
Create a funnel or use one you have to add the baking soda.
Pour in the 1/4 cup of vinegar and food coloring and watch it erupt!
Fun facts:
Mixing vinegar and baking soda produces carbon dioxide….this is the same gas that is found under the earth which causes a volcano to erupt.
Have you made a volcano in a bottle with your kids yet?
