It turns a dark brown color..I recommend getting a bobbypin and stretch it open so it looks like this: ______________________ and use it to stir the weed that's in the bowl for the vaporizor. I can get better hits that way and I can catch it usually before that nasty "burnt popcorn" taste as referred to above hits my lips (thank God! iccccckky!)

And my friends, take it from me, don't smoke the remains of the vaporizor bowl in the bong. It is absoultely disgusting. Not only does it give you the nastiest aftertaste the smoke smells like dog crap. Bleeeeeahh!!

I love the vape, I always "hit the floor" I kneel when I hit it.. gotta make that shit whistle!
