haha funny story:
my friends thought they were cool, so they did this with a 3 liter bottle and ALOT of dry ice and then they tied a big (bout 15 lbs i think)
rock to it and tossed it into the pool, in the center of his apartments (sounds kind of like a bad idea already)
about 6-7 seconds before it blew he could have swore it moved, then all of the sudden it floated up to the top......
needless to say they took off like crazy
a couple seconds later KABOOOOMMM!!!
they are back in their apartment and about 15-20 min later the police and a fire truck show up.some ppl gave them his description but his neighbors covered for him and he hasn't gotten in trouble, yet.....
this is really a true story believe it or not
