well, with a bc vaporizer it isnt as healthy as ones that use a heat gun (volcano vaporizer) so when the bc works it still burns the weed a little bit, there is a really good way to make a really easy heat gun that is really good and really healthy..... Heres what you will need: 1) A Heat Gun prefebally (sp) with a way to control the heat off it... this one is perfect click here. 2) If you clicked the link you saw a bit on the end of that gun, you need to get that also, and get some screens, the bit goes up in smaller chambers, so you put a screen in the smallest chamber and put your pot on top of that then put another screen to secure the pot, (if that is unclear then you should email me or instant message me)

OK, now you need a brass bit that will fit onto the top of the heat gun bit.... now find a plastic tube that will stay on the brass bit, get a freezer bag and a hair tie, and connect one end of the tube to the brass and the other into the bag. Then wrap the hair tie around the bag and tube until it is tight enough, now let the heat gun heat up. I know that is confuzing on here but just email me and i can make it clearer.but You now have a volcano vaporizer that isnt 500 dollars. I came up with this with a friend of mine. hope it helps
