Austin-based Grav Labs put their mark on the industry with the awe-worthy efficiency and thick-as-fog clouds of the Gravitron. True to their simply scientific niche, this straight tube pipe steps it up a notch with two subtle differences: a honeycomb percolator and the durable Dewar’s joint. The ever-reliable honeycomb perc design enhances the cooling and detoxification functions of water filtration. Linked by the two-pronged Dewar’s joint, this piece is both intensely smooth and powerful. Take the temperature in either direction by filling your pipe with hot water for a vapor effect or plop a few cubes in the ice catcher for an exhilarating inhale! The crisp 90-degree angles and polished glass give it a look to suit a laboratory or Apple store. If you like a little pop to your piece, the black option includes a colored perc, base trim, and flared mouthpiece. All in all, it stacks up to a sizeable 16".

Please Note: Grav Decal colors are picked at random - the color selection refers to the base and lip of the piece.

I love this bong

A step up from the old school bongs I still love. The ice catcher adds extra cooling that makes the big rips I get even smoother.

Cool straight tube with a twist

It looks like a simple straight tube, but the Dewar's joint and honeycomb perc really set it apart from other tubes.
