take a vitamin water/gatorade bottle and buy a top end to a socket for a socket rench its like $5, after you go these two things poke a whole on the bottom SIDE of the bottle not the bottom itself, you need to put the socket into the top of the lid so your going to need to get a knife and cut a little whole, and push the socket into it, have it as tight as it can, put some herb in the socket head, fill the water bottly while covering the whole at the bottom, then screw the cap on, light the herb, unplug the whole at the bottom, and if done right when the water from the bottom starts to empy the bottle should fill up with smoke, then unscrew cap and mother fuckin' enjoy
