Guaranteed to zazz the absolute SHIT out of all of your buddies, Hoss Glass' double cyclone disc build-a-bong base is one part an efficient diffuser and one part absolute showman!
At 9.5" tall, this 7mm thick piece of gloriousness will churn and spin your smoke around in such a way that you will almost NEVER want to see it stop.
But that would just be silly, now wouldn't it :)
Peep this shit in action!!
