Make a papier mâché volcano that actually erupts

This experiment rocks!

Make a papier mâché volcano that actually explodes!

Make a spectacular volcano using our simple paper mache recipe – then, add the ingredients to make your lava, and stand back to watch some incredible science magic.

The papier-mâché and paint will both take a while to dry, so it's best to spread this activity out over a few days. We promise it'll be worth the wait once you see the results!

  • Foil
