I made a homemade vaporizer out of a candle, a sobe bottle and a can of pringles and it works great. I took two good hits off of it and i was crazy high. I emptied out the weed the next day and it looks like it's got another 10 hits at least in it so that's always a good thing. It's a bit different if your used to smoking it because you don't get so mellowed out and tired, it's more of a celebral happy high, at least for me.
I just bought some lab equipment so that i can run some experiments and determine efficiency and other factors. this is just a thought but has anyone ever thought about condensing the vapor into a liquid?
