[quote=LURP;223892]Once you have obtained the butane, you need a pipe that measures 1.5 to 2.0 inches in diameter, is 16 to 24 inch long and is made from either polypropylene (PP) or polyethylene (PE). Basically, the bigger the pipe, the more bud it can hold. Do not use PVC piping because it can be a health hazard. Either PP or PE piping works best and can be found in any good DIY store. Each end of the pipe will need a cap. You should be able to get some PP or PE caps at a home improvement store or someone can make them for you. If you cannot find any suitable caps, you can try using large bottle caps and 'blue tack’ to hold them in place.

I watched some friends do this and they used 3 cans of super filtered butane
for one pull...it was on pvc... they got tons of oil out and they used a coffee grinder...the pvc was about 12 inches long and full about 3/4 with very finely ground leftovers dangerous...hell yes....he dripped it into a glass baking pan so it made a thin layer over it...heated it up just slightly in an open oven after wards......then used a lighter to ignite the left over butane that was trapped in the bubbles...will i try it? probably not.....im fine without it. ill stick to ice hash with the wonderful bubblenow bubbleator
