Yo dude, if you wanna do some hot knives just take two butter knives from your kitchen and lay them on your stove burner so that the tips of the knives heat up. Once the tips get nice and hot pick up a small piece of dope with one knife, (it should stick right to it with the heat) then put the other knife on top of the dope and it will start to smoke. You can either inhale it right from the knives but to avoid burning, run the smoke through a pop bottle cut in half and just inhale through the mouth. Enjoy!
