Here's how to make a safe and easy chemical volcano using two common, inexpensive household ingredients.
Time Required: minutes
- It's incredibly easy to make this volcano. Basically, you pour the hydrogen peroxide solution (found in pharmacies and grocery stores) into a small bottle. When you are ready for the eruption, add a packet of quick rise yeast to the bottle. Stir in the yeast or swirl it around the container. Watch your 'volcano' foam and fizz!
- If you're seeking more exact measurements, try a half cup of hydrogen peroxide with 1/2 tablespoon of yeast. If you like, you can build a model volcano shape around the bottle using clay or a paper cone.
What You Need:
- quick rising yeast
- hydrogen peroxide
- small bottle
- measuring cups (optional)
- paper or clay 'cone' (optional)
