With this thread I hope to bring out a few good ideas concerned with the ctype of lava, ice and snow. here I have listed some of my ctype ideas. feel free to post your ideas.

ice(gas) - good solid rocket fuel

ice(lava) - on wiki, generates solid/liquid mash

ice(bomb) - disappears when warm

ice(dest) - BOOOM!!!

snow(sing) - catelite's snow nuke (requires extra property editing)

ice(gbmb) - destroys any clay dust cities

lava(plsm) - lasts a long time

any others? I might make a library of these creations.
