Lol, canfan backwards....my buddy had a twelve inch that was open blowing out that he would constantly throw burning cigarettes through and hed pull leaves off and toss em through it. Kinda to prove he was a badass, then hed have to shut it down before we left and clean the thing out cause the leaves would stick in the spinning part. So i figured id be the badass one time when i was trimming and i throw a whole top cola at my carbon filter canfan scrubber combo thats sitting on the floor. Well it was a good toss and the bud flies right into the top....and then floats up in the air infront of everyone till we got done laughing and went and took it out of the airstream it was hovering in. Not as badass as my buddy but twice as funny
