ok if you don't have a bong or you can't get one you probably have made a ghetto bong or two. a common way is using a pen and foil/soda can. NOW every one goes
"foil will make you dick fall off"
"GO DOWN TO THE HEAD SHOP AND GET A BONG FOR $14"
good observations, but if your under 18/lazy but also want to keep your dick attached heres a simple down pipe.
1. take an old arial, from an old remote controlled car/radio
2. MOST IMPORTANT, You don't know what craps on the inside of the arial so take a shallow tub and fill it with boiling water and washing detergent, mix and submerge both the parts for a good 10 minutes at least and swish them around occasionally
3. get a glitter pen(the pens with spakling ink) with a metal ball casing
the piece that the ink rod pokes out of so you can write
4. get a hammer and lightly tap the pen tip into the down pipe until it cracks it a little
5. take some masking tape and with a 4 cm piece attach the bowl onto the down pipe
