oh yea i got some stories, we blew the door off the hinges with a water chage on a porta john when one of our friends was in there shitting, because it designed to blow straight and and just big enough hol for hinges we new it wouldn't hurt him but it literally scared the shit out of him, he jumped out with pants around ankles. He was mad at us for the rest of the day. but the water charges we used those to gane entry into houses and building, and the reason why was because they were quieter so it stil allowed us to have the element of surprise.
