Two knives, a 2 liter and some bud.
Heat the knives up on the stove. Electric stoves with the coils work better so you can stick the knives in until they turn red. Take a 2 liter and cut the bottom off.
Once the knives are hot, take a little bud and touch one knife to it, it'll stick then touch the other knife to the other side, stick it under the 2 liter and begin sucking.
It's easier with two people but it's basically vaporizing the bud so a little bud goes a long way.
