Materials:
-Baking soda
-Vinegar
-Plastic cup
-Food coloring
-Large container (like a bucket)
Instructions:
- Pour 1/3 cup of baking soda into the plastic cup.
- Add a few drops of food coloring to the baking soda to make the “lava” look more interesting.
- Position the plastic cup in the middle of the large container.
- Pour 1 cup of vinegar into the container and watch the “volcano” erupt.
- Once the eruption has stopped, take a look at the inside of the plastic cup. You should see a mound of baking soda and food coloring — this is the “volcano.”
- To make the volcano erupt again, just pour more vinegar into the container.
