This is a great activity for summer camps, science fairs or just a boring Sunday at home.
Things You'll Need
- Brown clay
- Water bottle
- 1/4 cup baking soda
- 1/4 cup vinegar
- Red food coloring
- Cardboard square (10 by 10 inches)
Set the water bottle on the cardboard square and pour 1/4 cup baking soda into the bottle. Add 10 drops of red food coloring to the baking soda.
Use the clay to create a volcano-shaped mound around the water bottle. Keep the structure on the cardboard square, and be sure to leave a hole at the top around the mouth of the water bottle.
Add small tree structures or rivers and lakes if you want to make it look authentic.
Add 1/4 cup vinegar to the mouth of the volcano. The baking soda and vinegar will have a chemical reaction, and the volcano will "erupt." Don’t worry, it’s not an explosion, just a stream of baking soda lava that will flow out of the top of the volcano.
Tips & Warnings
- Be sure to set this activity on plastic or do it outdoors since the cleanup process can be messy.
