Cavorite can be made inert or active by a very precise pattern of heat shocks. But is just isn't practical.

The process is very precise and complicated (otherwise it might be activated by mistake, or maliciously). Every piece would need its own highly insulated and controlled mobile furnace, and that's just crazy. I need a better idea.

Should we control cavorite by folding it? Or should we roll it like a window blind? Or should we build little motors for rapidly opening the cavorite sheets? Or do something else?
