GRAV’s instagram channel is becoming a little notorious for our Ghost Function Videos. Somehow we manage to film our pipes being smoked without any living humans appearing in front of the camera. Our most recent video is the trickiest one yet. Our Gravitron, the world’s first all-glass smoking system, requires some complex operation to say the least.
In honor of the Gravitron’s 14th birthday (and 14 years of GRAV being the most innovative name in glass), we’ve outdone ourselves with a video that’s spookily ingenious. Take a look and let us know how you think we did it in the comments below!
