Tips & Warnings
- Use wadded-up newspaper balls around the bottle to give the volcano its shape under a layer of plaster or papier-mâché paste, but make sure the surface layer of the volcano is solid, so that it can be sealed for re-use.
- If the lava is too thick, add 1 tbsp. water to the soap mix.
- To re-use the volcano, simply clean it off with a damp rag.
- Do not attempt to seal the bottle once the vinegar is added to the baking soda mixture--the resulting pressure could cause the bottle to explode.
