haha that was sweet...i like the car alarm the second one set off.....we used to do something like that when i was younger, except we'de take a 2 liter bottle, rip up a ton of tin foil and stuff it all in the bottle. then take some draino or even better was RedLye drain opener pour it in, squeeze the bottle (to give yourself some time to put the cap on) then shake it, and throw...the bottles would get huge as hell like that and blow!
