We got the cops called TWICE because of dry ice bombs from my rats. Gatorade bottles do the best! Let them expand and then run, grab, throw, and run! BOOM. Bottles are like rockets! That is the only down side to breeding my own feeders now...lol. I do use dry ice for euthanizing....
We got like 30lbs of the stuff last 4th of July and dropped in the the neighbors pool.
