Bah! A mere trifle. Try an 11 inch diameter aluminum "capsule" pumped up somewhere over 600 psi with nitrous oxide sudduly cutting itself in half, ahead of schedule. BANG! Followed by the sound of a large chunk of aluminum ricocheting around about 10 feet from you.

Oooh, even better: a 600-psi liquid fuel bipropellant rocket engine undergoing hard start... so hard it tears itself to bits and shakes the building enough that all the dust seeps out of the ceiling tiles making you think it's smoke and the building is on fire... It's even better when you just told your boss "Don't start it!" and he does so anyway and sets you back two months...
