sqeeze a empty soda can about halfway to full implosion

get something like a corn cobb holder and poke some holes on the most level surface of the thinnest metal of the can (not the opening face or the bottom)

make a pea sized "carb" hole on the opposite side of the can as the tiny holes.

Cover the hole with a finger when you fire the bud and inhale....after you remove the fire from the pipe, uncover the "carb hole" and inhale some more.



thats all....:thumbsup:
