well its not really a mistake, but it kept a lot of platic moms from seeing their plastic sons again......
I used to collect Micro Machines, the military line to be exact, and one year i bought a sh*t load of fire cracker ranging from the little pittly things to m-80's and Dixi Dynimite for 4th of july, well i had a whole lot of them left over and decided, HEY! Im gonna recreate the Gulf War in my sandbox.... by burying the firecrackers and then setting up a battle sceen over them and then lighting the firecrackers, surpisingly most of them survived, others were pretty realisticly damaged, and others just plain vanished!
then there is this sorry excuse of insanity
Then when i was about 14/15 my uncle the chemist decided it would be a smart thing to teach me a bit of chemistry and how to "experment" with chemicals... well one day he left a large container of Highly Volitile acid at my house, (i cant remember what type it was but it sure disolved plastic) and i had fun the rest of the night torturing Cobra troops and Teenage Mutant Ninja Turtles, Talk about mutations lol but luckly most of my TMNT's i left undamaged and still have, but every now and then ill still find the acid eaten head or limb of a cobra trooper.....
