yeah man we used those for ages too but we call them parachutes even better than that for getting stoned as is spots! that is when you roll a small bit of weed into a little ball heat up two butter knives till they nearly(but not quite)red hot. cut off a coke bottle near the top to make it like a funnel shape. take one of the hot knives touch the bud which will then stick to it rub it with the other knife and suck thru the funnel. only prob someone has to do the knives while the other sucks thru the funnel. if you dont get it all tell me which part and ill try explain better
