What you are all talking about is called SPOTTING...its big here in New Zealand. You will need 2 knives, a glass bottle with the bottom removed, and a tin lid to put over knives to help them heat faster. The knives need to be red hot for each SPOT you do. Make your spots up on a wooden chopping board or something similier, when the knives are hot lightly touch the spot with it and it will connect to the heat, then push the other knife on top of the spot and hold under under the bottle and inhale. It is easier to have 2 ppl to do this, 1 to drive the knives, and 1 toking, then swap. My hubby has made me a self spotter holder which I will try to get you pics of us using so you can make one.

You use alot less weed by SPOTTING it and you get shit-faced. Don't make your spots too big cos doing it this way you get alot more smoke.
Hope this has been some help to you....GOOD LUCK
