Well me and 2 m8's one day got bored and we had some acid stuff at home in a bottle when u mix this stuff with tin foil and put in a coke bottle for instance it will inflate and make a loud explosion ^^
well one day we did it and we didnt put enough liquid in so the bottle just inflated and never blew up so this idiot :P aka me

(when i was 14 ) went up and opened the lid and it had pressure so it let out a load of acid some went into my eye so i realized there was a public pool about 500 mtrs down the raod to i sprinted to the pool jumped in and washed my eye luckly i never went blind :P then i realized i jumnped in with my phone / ipod
