Another incredible design collaboration from GRAV! The Bates and Worm colab-created diffusion pump perc is a wild ride for your rip to take. These water pipes have a surprisingly high water line and require a big pull to get the pump going, but once you are hitting it, it's all smooth sailing. The water is pulled through the diffusion pump and the glass bead separates the hit into a thousand individual bubbles that move through the second tube and up into the mouthpiece. This is one of the most scientific designs you will ever come across in a piece.
