These "sploofs" I have always known as hootimatics, and have found the large jolt or rockstar cans to be the best. Poke a decent amount of holes in the bottom and stuff it with dryer sheets. It works very well, but I don't recommend it. First off, I don't particularly like my room smelling of dryer sheets, and because it's always seemed to get people more suspicious then incense. Incense is what I use, because I love the smell and it works... just say you use it for meditation and relaxation: you're not lying. I used to box my room practically during the night with friends, then burn incense in the morning, and we we're always alright. I know my mom always suspected tho. Worst come to worst just crane your neck out a window with a pipe or something. You can also pack one-hitters in bongs, make sure you don't leak, and blow it up and out the window. I prefer that to bounty sheets.
