    Class is planning to build a volcano to have on display for open house. I haven't ever made one of these before and I've been reading up on it. I'm hoping someone here has some experience with it although I don't see a lot of science teachers post.

    1. I want something a substantial size to that means a 1 or 2 liter size bottle? I was thinking 2 liter but would that be some ridiciolous size that requires a lot of work to build the bast?

    2. Paper mache or homemade clay? It seems the majority of build volcanoes use one these materials. Anybody have a preference? I haven't use paper mache for ages. Is that where I have to wait until it completely dries before I can add to the base of the volcano?

    I've built them with students, but on a much smaller scale and with bathroom cups. I've never done the full moutain base, so can't help you there. Sorry!!

    We use a baby food jar for the baking soda and vinegar. First we model the base with aluminum foil, then cover the foil with newspaper dipped in a glue/water mixture. When dry, we paint the whole thing, and let 'er erupt! Oh, I forgot to say that we shape the base to model the Big Island of Hawaii, which is where our active volcanos are.
