SHOTTY
You make a normal 20oz coke bottle bong, except instead of a downstem/bowl you use a small metal tube you can fit a cigarette in. A perfect example of this is the lowest/fattest part of old school car antennas that telescope. In fact one of those is really your best bet if you want to "borrow" one. Then you fill the bottle with just barely enough water to cover the bottom of the tube. You rip a couple inches of a cigarette off and shove it in the tube. Then you grind up the weed, and sort of dip/press the tube with the cigarette bit in it and get a bunch of ganja stuck to the end. After all the weed is smoked, the flame will hit the cigarette piece and it'll instantly crumple and snap.
You get thick, nasty, yellow smoke. It tastes horrible and you will probably cough up a lung. But one hit from it will get you completely ripped, every time, with just a tiny tiny amount of shake.
