Materials:
pipe- no plastic or PVC!!
cake pan
pyrex dish
5X refined butane (other will work but leave you with bad butane taste and smell)
sreen material
cap with drilled hole
razors
boiling water
Well ventilated area (just go outside, its the safest)
Trim/buds - chopped fine as possible, i use coffee grinder
fill pipe 2/3 full DO NOT PACK! put screen on and set all materials up outside. bring water to boil inside or away from BHO area. take boiling water from heat and pour into cake pan. immediatley put pyrex into the water.**make shur pyrex does not get water into it** hold pipe, screen down, over the pyrex and start the butane through the cap hole. (i blow the first poof of butane away from pyrex cuz it blows [plant material sometimes)
once the liquid comeing from the pipe turns back into clear the plant material is spent and ready to be tossed. use razor to pop remaining bubbles of trapped butane, scrap it all up and enjoy!!
DO NOT SMOKE WILE MAKEING BHO, AND BE VERY VERY CAREFULL!!!!
