i invented the "Smoke-a-Cola", with the same bottle as the base, and a 16 oz on the top. it had a volcano effect as the smoke would rise through the mouthpiece of the round holiday coke bottle. (they're from around christmas time designed to look like ornaments for a tree)

^They come out around the holidays LMAO, I was really expecting to come into this thread and see an 8 ball or something.. Not a fan of home-made, but that one is pretty sweet.
Yo, don't use those pen tubes. They got tons of chemicals that release at low temperatures. Lower than the smokes temperature.
Well if it really releases plastic fumes its much worse than cigarettes. Hold on I'll find some data edit: yeah it can cause asphyxiation and death, but thats with repetition. I'd highly reccommend using something else though, as the plastic fumes can stay in your lungs for quite some time. Just google some shit I don't wanna copy and paste
no plastic is burning. therefore, safe. did you know broken glass burns too? dont smoke out of broken pieces. and stop judging whether peoples bongs are safe for 100 years of use people, i already threw this one out
