Be treated to a cosmic exhibition as you smoke and watch water drip out and fill back up the water chamber! Even time travellers have to chill and relax. And if The Doctor on BBC's hit series 'Dr Who' has to choose a pipe, it'd be this one. A Time Pipe for a time traveller. Everything about this oil rig screams aesthetics. The light brown and blue combination is visually interesting and will make this bong stand out in any collection. Even the bent mouthpiece amps the aesthetics of this pipe. Two honeycomb percs are located in the two recycler arms and they cool and filter your smoke. The honeycomb perc is made up of a disk perc with dozens of small holes that diffuse and divide smoke that passes through them. This allows the honeycomb perc to diffuse smoke better than most percs. Water, containing smoke, travels through the recycler arms, bubbles through the percs, then continues further up until it reaches the chamber near the mouthpiece. Since the smoke then travels a short distance to your mouth, you get fresh and better tasting hits for your relaxation and enjoyment. Color of the handle/mouth end may vary. High-quality borosilicate glass confers durability.
