i cant make lipo's go bang!!!

lets see....never had a genuine failure yet, both failures caused my ME and the rest were on purpose.
the maxamps cell i tryed to blow up...well....
dead short.....nothing
gave a single cell 12V and pumped it with 100 amps from a car batt...nothing
nailed it...nothing
hosed it..nothing
douced in some nitro and set it on fire....nothing!!!!
the ones that did fail were caused by gravel rash under heavy load, that one caught fire so i ripped off the top cell (while on fire) and tossed it away, saved the pack and now it's a 4s.
the other one was left plugged into the MMM so when the MMM died it took out the lipo too....no fire luckily cause it was in my car
