not only the dangers of the cap IF you could extract it the procedure that is described is insane. for one you probably couldn't get PURE ethanol. Secondly pure ethanol has a flash point somewhere around 55F - meaning it would take a little spark to set it on fire, let alone mixing this crap in your blender. Then it describes heating this mixture?? Seriously?? You'll probably end up burning your house down before you could even get the pure cap. Easier to just buy "The Source" or other extract. Might cost you some, but cheaper than hurting yourself or burning down the house.
