Take a pop bottle cut it in half and find a bag(one like the newspaper comes in) that your gotta stretch over the cut end.(Gives good suction) Then take you bottle cap and cut a hole for a bowl. I usually melt the sharp parts of where I cut to get the hole big as I want and soft. Put tinfoil in the hole for the bowl. Poke holes with a tooth pick or something small. Tape the bag on so it stays tight and no smoke escapes.Place weed in bowl turn a light on it pull down on the bad slowy and viola a sweet iron lung hit. If you do these I gaurantee you'll get high.
