I would like my students to build a volcano. It's cheesy and doesn't really
teach em anything but it's still a good time for all. Does anyone have a
good model? Surely there is something better than paper mache? I was
thinking of letting groups of two build one each and then I would supply the
chemicals and let them set them off in the playground.

Thanks

marc
