Easy to Use

Smoke like a pro with this GRAV Labs Gravitron gravity bong. When you’re ready to toke, you just fill up the cylindrical base with water to the bottom of the logo, add the bottle insert and packed bowl, then light up the bong. Once the internal chamber fills, you pull up the bottle, lift the bowl and inhale smoke from the downstem for a fuss-free experience. Since the streamlined design has no carb or percolator, this gravity bong proves simple for even novice smokers to use and offers fast, easy setup when you don’t have much time to toke.

Powerful Pressurized Hits

Conserve your flowers by indulging in the powerful pressurized hits delivered by this GRAV Labs Gravitron gravity bong. Because the unique funnel design forces smoke upward into your mouth, you always get the entire hit with less plant material. The 11-inch sizing provides this gravity bong with a large chamber for smoke to gather, making it a great choice for experienced smokers who want to get the full effects of their flowers. Additionally, the glass construction means this gravity bong doesn’t add chemicals to your smoke.

Simple Yet Elegant Look

Showcase this GRAV Labs Gravitron gravity bong in your home decor thanks to its simple yet elegant look. The clear glass and discreet black accents and Gravitron logo let you display this bong in innocuous places without anyone but other smokers suspecting its anything other than a decorative piece.

Elegent and powerful

Mighty punch. New fave piece. Easy to use, easy to clean, and does the job

Elegant Refinement

Fancy! Love this glass, a little too much. When this is cleaned up (easy 2 do) it can sit amongst holiday China, burial urns, Hummel figurines, that “fake” shrunken head you got while on a conservation safari. It always seems to be looking your direction no matter where you are in the room. Is that… drums?
