Grav Labs Bates/Worm Outside Diffusion Pump Dab Rig

Calling all science fair nerds out there! This one's especially for you: Grav Labs (and a collab with Bates/Worm) has graced us with yet another fun contraption for smoking your favorite flower with an outside diffusion bong. What does that mean exactly? Instead of passing the smoke through a series of chambers and percolators inside of the water pipe itself, this outside diffusion system funnels the smoke and water into a separate pipe that creates some amazing bubbles. If you haven't tried outside diffusion yet, consider this a first taste brought to you from Dope Boo. In addition to the dope outside diffusion system, this bong is high-quality all around, with thick borosilicate glass that reinforces the bong's durability and makes it easy to see the smoke show happening inside the bong. Since this bong is also a dab rig, it'll work with any female 14mm 90 degree accessories.
