Grav Gravitron 2.0 Bong

The 11-inch tall GRAV Gravitron 2.0 Water Pipe is a new and improved version of the crowd-pleasing original Gravitron that's five times thicker than its predecessor.

The Gravitron 2.0 gravity bong features an upgraded grommet made of platinum-cured silicone to ensure a tight seal while the flanged neck at the top makes it easy to lift the bottle when taking a rip. 

The water pipe/gravity bong is equipped with an 18.8mm female joint and comes with an 18.8mm male herb slide.

The Gravitron 2.0 is easy to use. Just fill the base halfway with water, pack the bowl with dry herb and insert it into the joint at the neck of the bottle. Then fire up the bowl while lifting the bottle.

Once the bottle fills with smoke, remove the bowl and place your mouth over the neck as you're lowering the bottle. You'll get a dense, pressurized rip with no loss of smoke in the process. It's fun, efficient, and a real blast to use!
