The NWTN Vesper Gravity Pipe (often called the Vesper Gravity Bong) is the full-sized, high-impact version of the Vesper design. While it shares the same smooth, rounded aesthetic as the Vesper Bubbler, it uses a different physics mechanism to deliver much more potent hits.
It is easy to mix these up because they look similar, but their functions are very different:
The Gravity Pipe (This item): Uses a "lift and push" water displacement method. It creates a vacuum that pulls a massive amount of smoke into the chamber, which you then force out by pushing the glass core back down. It is built for maximum efficiency and intensity.
The Bubbler: Uses standard suction. You simply pull through it like a regular pipe, and the water filters the smoke as you inhale. It is built for pacing and smooth, casual sessions.
Color Selection
Baltic Amber: A deep, translucent golden-brown that looks like mid-century vintage glassware.
Emerald: A rich, jewel-toned green. This color is currently a best-seller and often goes out of stock quickly at major retailers.
User Experience & Cleaning
The "Vase" Aesthetic: Because of the smooth glass and absence of external "science-lab" looking parts, this piece is designed to be displayed on a bookshelf or bar cart as a piece of decor when not in use.
Maintenance: Since this is a 4-piece modular system, you can pull it apart completely. Using your Nine9 99% Isopropyl Alcohol is the best way to maintain it—just pour a little into the shell and core, add a bit of coarse salt, and shake. The 99% purity will ensure the amber or emerald glass stays crystal clear and streak-free.
