i've done it, i've only seen really poor people do it though since they had nothing else to smoke out of(not saying that ya'll are poor, i'm just sayin, u know). Anyway, I dont use the bottle technique since it makes it taste kinda funny to me, i just press the weed together with the hot knives and put the tip of the straw as close to it as i can and suck real hard to get as much smoke as i can.
weedheaduknow Reviewed by weedheaduknow on . anyone else try "knife hits"? cut the bottom off a 1 liter or two liter bottle, then hold the top small hole to your face and inhale as one or two butter knives are placed on the paper plate that is holding the crumpled up cannabis. Very hot!!! Don't use too much.. It was called "knife hits" back at my day!!!! I got so stoned, but I have never coughed so hard in my life. What was the high like for you? Rating: 5
