this is my homemade bong that i made in 10 minutes. Its 45cm tall. It has a carb hole on it too. I spent only $1.00 for the plastic and i found the bowl thing laying around in my house.
it works really nice i also put ice in the top and it acts as an ice catcher and it gives a nice cool hit
Niceeee bong dude =] Cool idea using common household items.. Lol I get those cups @ the St. fair every year... there might even be one lying around right now. I should make one too... my only bong is a crappy Vitaminwater one w/o a carb
