so i have to make a poor cities for the next play im doing and there will be homeless people. i think that have a trash can with smoke coming out of it would be a nice effect to do. i have a metal trash can already. i cant remember were i heard it but i know i did, that dry ice smokes well. so i was planing on doing a search on how to make dry ice smoke. but if you guys know of a easier way to get it to look like smoke. please let me know.
