So basically I smoke out of my milk jug gravity bong everyday, and having been using the same one for at least 6 months and perhaps even as long as 9, it was basically almost black on the top 30% of it, and today my friend just saw it and was like "HOW HAVE YOU NEVER SCRAPED THIS". So he then perceded to scrape it with a knife for the next 30 minutes, and I seriously think he got a QP worth of resin out of it.. no joke. The ball is about 5x the size of a pinball, and I just took a piece approx, 1\100 the size of the ball and put it in my gravity bong and it bubbled and turned red with heat and finally at the very edge of pulling my milk jug out of the water it falls through and my jug is filled with THICK white smoke and I take the hit (by far the biggest hit I have ever seen in terms of thick smoke) and I feel like I just took a hit of the flamest weed I have ever smoked. It basically knocked me out, and I'm twitching a little bit right now.. wtf..
