Variable pressure gas. Heat to expand, cool to contract. Non-flammable.

Makes FOG when mixed with WATR. Makes WATR when mixed with OXYG, which then turns to FOG. When placed in a container with URAN will undergo a reaction in which the BOYL expands, creating pressure, causing URAN to heat up, causing BOYL to create pressure, and so.
