Why does everyone suggest these fuckin hard and dangerous methods for a newb like the can pipe. You can either cut yourself or get that disease.

Use an APPLE!!!!
Poke 2 holes with a ball point pen and you're done!
I remember breaking my ass trying to make these rediculous bongs but an apple always works.
Penetrate the top where the stem is and the center for the mouthpiece.
Place weed on top where stem was
Light it up and inhale through center hole.
If you stabbed it from one side to the other side of the apple, then hold onto 1 hole with your finger.

You want a healthy way to smoke?
It's too hard to make a good bong, so you're better off just buying a cheap one.
