Yes dont use plastic.When heated plastics tend to release carcinogens and its not worth risking lung cancer or lung damage.This is especially true for acrylics also. And btw I dont have foil in my house ever.I've no need to. And its great livving in the heart of a metro area.Just a couple blocks or less in any direction and I can find anything I need.lmao Which is precisely why I wont ever move from the city.
Ok, a few suggestions: 1) Never put plastic in contact with fire. 2) Avoid coke cans at all costs. I suppose it won't kill you to use one, I've done it before, but they're a baaaaaad idea. 3) You don't need a socket to make an apple pipe, you can make one with only an apple. Simply carve a funnel-shaped hole in the top instead of a round one. 4) Although I've never tried it, many people swear by the hot-knife method, so that's probably worth a shot. 5) A very ghetto bong can be made using a pen, a plastic bottle, and gum for sealant. The bowl is the trickiest part, and it involves keeping the bottom of the bowl far enough away from the pen tube so that you don't get burning plastic.
