Solid-to-gas reactions

TATP and DADP neither detonate nor deflagrate they are rare entropy explosions. The effect is from rapid dissociation of weak atomic bonds within the acetone peroxide molecules, not from a chemical reaction as seen in all common explosives. Acetone peroxides require neither heat to form nor do they release heat when they dissociate the effect is similar to the solid-to-gas reaction that deploys automobile air bags.
