has a quick question involving home-made crack
Basically, SWIM uses an Evian (or other similar) bottle, empties a quarter of the water out, makes a hole in one side of the bottle in which she inserts a small tube to pull on, tinfoil with tiny holes on top of bottle, then ash, crack and voila! She has her pipe ...
The other week a friend of SWIM's asked her why she didn't put a "shot" hole on the other side: this is a technique SWIM is familiar with from back in the day when she used to smoke pot, i.e. you put a small hole in the bottle/pipe on the other side from where the tube is, place your finger over the hole whilst you pull on the pipe and then release it at the last minute so that air gets sucked in and pushes more smoke (and air) into the users' lungs. SWIM has never thought to do this with a crack-pipe before though and for some reason she just always saw it as something stoners did. Does it work as effectively with a crack-pipe? Is there any point doing it?
