Product Description
Gravity bongs started as a cut-up soda bottle and a bucket in somebody's bathroom. The Grav Gravitron keeps the physics and drops the mess. It's a glass gravity bong made entirely from borosilicate glass: a water base, a lift bottle, and one dense, pressurized hit at a time.
Version 2.0 uses glass five times thicker than the original Gravitron, plus an upgraded platinum-cured silicone grommet that seals the bottle into the base. No leaks. No smoke drifting off while you line up the bowl. A flange at the top of the neck gives your fingers a real grip, so the lift stays smooth even on round three.
How the gravity bong works: Fill the base halfway with water. Pack the included funnel bowl with dry herb and set it in the joint at the neck. Light the bowl as you lift the bottle, and the rising bottle pulls smoke through the bowl until the chamber fills. Pull the bowl, put your mouth over the neck, and inhale as you lower the bottle. The water pushes the full load of smoke out, and nothing escapes between the bowl and you.
Fair warning: a gravity bong hit lands harder than the same bowl through a standard water pipe. Start with a small pack and work up from there. Your lungs will thank you.
The Gravitron is the centerpiece of a group smoke sesh, the one everybody wants a turn on. It's also one of our most-gifted stoner gifts, a solid pick for the friend who still talks about their college bucket bong. Prices run $63 to $148 depending on size.
GRAV® Large Gravitron® (G04.V2)
The bigger V2 at 11 inches tall, with the largest chamber and the biggest hit. The 19mm female joint fits any standard 19mm male bowl, so your favorite bowl from your other water pipes works here too.
- Height: 11 inches
- Joint size: 19mm female
- Includes: 19mm funnel bowl
- Includes: platinum-cured silicone grommet
- Material: borosilicate glass, 5x thicker than V1
GRAV® Medium Gravitron® (G03.V2)
Same gravity mechanics in a 9-inch body. The Medium Gravitron fits on a smaller shelf and stashes easier, and it still pulls a hit that'll make you sit down. The 14mm female ground joint fits any 14mm male bowl.
- Height: 9 inches
- Joint size: 14mm female
- Includes: 14mm funnel bowl
- Includes: platinum-cured silicone grommet
- Material: borosilicate glass, 5x thicker than V1
GRAV® Monarch Gravitron® (G04.MON)
The tallest option at 12 inches. The Monarch Gravitron works exactly like the standard Gravitron, with a scalloped borosilicate glass body that looks good enough to leave on display between sessions. The large glass chamber fills with thick, dense smoke for an enormous hit.
- Height: 12 inches
- Joint size: 14mm female
- Includes: 14mm funnel bowl
- Includes: silicone grommet
- Material: scalloped borosilicate glass
Care: Change the water after every session. For a deep clean, shake isopropyl alcohol and coarse salt through the bottle and base, then rinse with warm water. Borosilicate glass handles the scrub, and a clean Gravitron pulls smoother hits.
