"Well..." Jake mused, drawing out the ll's as he thought. "I guess it would have to have a certain amount. But really, it wouldn't be water because that temperature is much higher than the temperature of water turning to gas. It really would be pure rock, if that makes any sense," he suggested. "As it is, well, I think our best bet is to freeze the lava into paths for people to run to safety on." It was the only suggestion that Jake could come up with. The only problem was, how would they know which buildings had people and which didn't? And for that matter, how often would Toshiro and Martha be able to do this? AFter all, changing the preferred shape of molecules took quite a bit of energy; inertia and all that. Ugh, he wished electricity would be of some use in any situation but, nope. He was pretty useless.
(I thought Martha was a mermaid? O.o I'm confused now)
