Whoa, what a long downstem, you say to yourself. Wrong! We’re not trying to make you feel bad, but this little toy is quite the bong accessory. Meant for the one and only Gravitron from GRAV Labs (it’s a high-tech gravity bong, in case you didn’t know), this bubbler bowl can be added to your Gravitron to make it the biggest bubbler you’ll ever see in your life. Ever. At 10 inches tall, this bubbler bowl is quite the contraption, but it’s actually an affordable accessory and an easy way to spice up your otherwise mundane Gravitron lifestyle. While you might think the Graviton already does a nice job of filtering smoke (which it totally does), adding in the bubbler gives you much more filtration. Using this Gravitron bubbler bowl with this added water filtration is perfect for those who find the Gravitron on its own to be too strong.
