i got the general idea from og oil extraction faq. i took a copper pipe and put an end cap on it. i drilled a tiny hole big enough to stick the tip of the butane in it. the other end is a hose clamp with screen attached. i stuffed it full of trim from the jar i keep and squirted a whole can of butane in it. use oven mits if you try it, that pipe turns freezing cold. dont smoke either, you will blow yourself up. then the juice drips out into a bowl, mine was a little green, but it looks like honey oil. so i did that a couple times, went to the store, and when i got back the butane was evaporated and i had honey oil i scraped up. it works, but make sure the butane dont stink before you try it.
