hash oil.----> butaine, steel pipe/with caps for end. drill hole in both caps...then add one cap....fill the pipe with trimmings and/or some buds if you want better hash oil. then screw on the finial cap.....stick one end of the pipe in a container...and run butaine into the pipe from the top. then you will get a oil dripping out of the bottom.
hash-- bubble hash is a very good method for making hash,
