this is a wicked way to extraction. bubblebags are much better w/o the carcinogens. i have found the butane extraction to be way too wasteful. the honeyoil is VERY hard to work with & sticks to everything, not to mention it is highly explosive while awaiting for it too evaporate. if you really want to try it get the most expensive butane you can find, (usually the purest), need a pipe w/capends, drill the ends for the nozzle of the butane on one end use a coffee filter to keep the buds in. when you disperse the butane keep the bottle tight against the pipe to keep the pressure coming out the coffee filter end. when it stops leaking out grab another can of butane, keep this up till butane comes out clear, wear thick gloves to keep hands from freezing. then sell it so that you dont smoke all the chemicals that are in the butane
