GRAV reinvents the iconic Gravitron.

After inventing the glass gravity bong in 2004, GRAV has redesigned the Gravitron for the first time in 17 years.

GRAV, the leading manufacturer of handcrafted glass cannabis smoking accessories, has redesigned the Gravitron for the first time in 17 years. When David Daily designed the Gravitron in 2004, recreational cannabis was eight years away from being legalized in a single U.S. state. Today, GRAV is one of the stalwarts of the cannabis industry, and recreational cannabis is legal in 17 states and Washington DC. And GRAV has grown with the industry - from one product in 2004, to two in 2007, to over 300 in 2021.

The Gravitron's bottle design dates back to David Daily's parents' garage, where he designed bongs from recycled materials while working as a mortgage broker during the day. Before the Gravitron's introduction, gravity bongs were made by cutting off the bottom of a soda bottle and dunking it in a bucket. GRAV's all-glass version brought the Gravity Bong out of the shadows and made it a collector's item.

The new version has been improved from top to bottom, starting with a ground glass joint and ending with a platinum-cured silicone spout at the bottom of the bottle. It's a thicker, heavier and all-around sturdier version of the company's namesake product.

The Gravitron produces large, efficient hits through gravity and pressure. The GRAV Large Gravitron is 28cm tall and comes with a 19mm funnel bowl. The GRAV Medium Gravitron is 23cm tall and comes with a 14mm funnel.

updates

- 5 times stronger glass thickness and more stable packaging
- The new flange at the top of the bottle neck makes lifting easier and safer
- The ground glass joint has replaced the shell adapter with rubber grommet
- Compatible with any 14mm (medium) or 19mm (large) shell
- Platinum hardened silicone grommet on the bottom for better sealing
use

Fill the base halfway with water, fill the bowl with dry herb and insert it into the port on the neck of the bottle. Light the bowl while lifting the bottle. Once the bottle is full of smoke, remove the bowl, place your mouth over the neck of the bottle and inhale as you lower the bottle. The Gravitron gives you a tight, pressurized hit without losing any smoke. Although it's considered the ultimate party pipe, the Gravitron is basically one of the most efficient smoking devices on the market.

CRAVITRON medium is available at onehitter.de. As is everything else from GRAV.
