Jeezzz. I have a mug at work made out of the plastic carry case that two 81mm mortar rounds come in, now that is WAR!!!! We use it for drinking games but the RMO had a fit when he found out, apperently the plastic is toxic or some shit. Never did me any harm, might explain my hair falling out though. Doing shots out of expended 40mm HEDP cases might be the reason to.
