Want to have a little fun while teaching your students some basic chemical reactions through science? Let’s make a playdough volcano erupt.
Create volcanos out of Playdough to serve as vessels
1/4 cup vinegar
2 tablespoons baking soda
1.) Use a funnel to fill the cavity of the volcano with 2 Tablespoons of baking soda.
2.) When you’re ready for the eruption of the volcano, use a funnel to quickly pour 1/4 cup of vinegar into the cavity of the volcano holding the baking soda.
3.) Take the funnel out of the cavity as quick as possible and stand back. The mixture will not explode, but it will bubble and spit and ooze out pretty fast once the reaction starts.
Why is There a Chemical Reaction?
An explosive chemical reaction occurs that releases carbon dioxide and water as the carbon dioxide escapes the solution bubbles. In a baking soda volcano, when you add the vinegar to the baking soda inside the volcano, the volcano collects the gas and form bubbles that flow like lava down the side of the volcano.
