Molecular Combustion

The ability to speed up molecules around an object. Causing an object to explod. Piper has this as her secondary ability, her first being molecular immobilization. She's been seen to have been able to blow up almost anything, with little or no limitation at all. With the exception of upper level demons in which, some are immuned to her power. The actually combustion becomes an almost fire ball like blast that is focused on a certain area of the demon, itself.
