LEGALIZE IT EVERYWHERE !!!!!!!!!!!!

obviously this is a way of doing a bho extraction, however.. I personally use 2 coffee filter. i started off with a turkey baster, although soon upgraded to a honeybee extractor (plastic so it doesnt freese your hands) and it had a lid that you screw the coffee filters onto. i have blasted into hot water before however you will loose a little potency if the water is to hot and then you have to deal with purging out water/butane. and i wouldnt let your hot water bath go over 115degrees if you would like to keep the majority of your flavor terps. btw butane evaporates at roomtemp anything above that temp with help speed up the process. 

no worries on how much water,  just luke warm, filled up halfway........its a lot better method, cleaner and more efficient.

interesting, ive always used the normal method of using a glass platter and scraping the oil together and then doing a purge. how much water do you use? ill have to try this someday.
