Women live longer because they don’t fill their refrigerator with Tannerite and then shoot it!
Tannerite is a brand of binary explosive targets used for firearms practice and sold in kit form. The targets comprise a combination of oxidizers and a fuel, primarily aluminium powder, that is supplied as two separate components that are mixed by the user. The combination is relatively stable when subjected to forces less severe than a high-velocity bullet impact. A hammer blow, being dropped, or impact from a low-velocity bullet or shotgun blast will not initiate a reaction. It is also designed to be non-flammable (the reaction cannot be triggered by a burning fuse or electricity), although its explosion can cause other flammable material to ignite.
Because it is sold as two separate components, it can be transported and sold in many places without the legal restrictions that would otherwise apply to explosives. (via Wikipedia)
