Get 2 knives that you don't mind getting ruined (BE WARNED THIS WRECKS KNIFES!!)
a tiny amount of pot about the length and width of your smalest finger nail
and the height of about half the length of your smallest finger nail
then get a small bottle and cut the bottum off
place the knives over a fire, lighter cooker fireplace whatever
if they're metal handled use a jumper or somert to pickup
when you recon they're right hot put the pot down on somert
and place one of the knives onto it firmly which will make it stick
then squeeze the pot between the two knives hard with the bottle close over the top so the fumes go into it so you can suck might take 2man job
but really really gets you high after like 2 it's shocking how much
you won't belive it untill you do it I recommend it
though it's damn harsh and is probably extreme bad for your health.....
ENJOY
