i like making my own pipes out of bottles and alumnium wrap
but mostly i smoke through the "wet" rocket, which is made out of 2 bottles big one and small one, cut off the upper part of bigger one, and lower part of the small one. make a bowl out of alumnium wrap and cap. ..].
the local yobs were smoking one of these in my garden recently. you can make a dry one by taping a poly bag to the cut base and using it as a diaphram. stuff it into the base of the bottle and pull it out slowly while you burn your weed. not as cooling but more portable. dificult to eat in a bust though
