Above is a picture of a really awesome volcano errupting that Maestro built. How cool is this? He had to mix the plaster, put it in the mold, let it harden, take off the mold and WAIT 24 hours (that's the hardest part for him!) to paint it, which he did, then waited to dry (more waiting? What?) then he put baking soda in the middle, added dish soap (which the chinese directions called "washing up soap") and vinegar and watch the erruptions commence! It was a bucketload of fun.
Wishing you your own fantastic lava experiments, ~Peacemom
