Got this email yesterday from 420 Science yesterday, apparently they are carrying glass now. Not a big fan of the small percs or the mouth piece angle, but the built-in jar is something different and enticing. Suffice to say, it looks like some pretty clean glass that would work great for vapor. I like how they added the lighter for size comparison. Link to Video " We teamed up with visionary artist Stephan Peirce to create a line of tubes unlike anything you've seen before. Based in our hometown of Austin, TX, Peirce approached us with the idea to integrate a jar into a water pipe and we love the designs he's created. The built-in jar provides a dual function. In addition to storage, the chamber creates a gentle swirling effect that aerates and cools the smoke. This results in a pleasing and refreshing hit."
