The Cheapest Possible Bong
1) take a sip of water (you'll need to experiment to find the right amount)
2) cup your hands to form an air chamber (as if you were holding an insect in your hands)
3) tuck a joint between the pinky and ring finger
4) hold your head down a little
5) inhale at the opening between your thumbs
6) spit out that disgusting bong water after your hit
...it really does cool the smoke and if you accidently swallow the water instead of spitting it out you can taste all the crap that got filtered out, so, don't accidently do that.
