The Gravitron is the namesake gravity bong from industry veterans Grav. Featuring an inner bottle with a silicone grommet and a wide outer container which allow you to create dense gravity fed hits in a clean and stylish package. The 5mm thick borosilicate glass ensures durability while the separate pieces make cleaning a breeze.

How to Use a Gravity Bong: Gravity Bongs are fun consumption tools that can deliver powerful hits of thick smoke and vapor. To start, fill the outer glass container with water, we suggest starting about halfway full although like any glass you can experiment and find your personal preference. Then slide the inner glass bottle all the way down and insert your packed bowl or swap in a 14mm-compatible consumption method of choice. 

To fill the chamber, light the bowl while gently lifting the inner glass bottle out of the water. Be sure not to remove the glass bottle from the water completely or your smoke and vapor will escape out of the bottom. Once full of smoke, remove the bowl, place your mouth over the opening and lower the glass back into the water, forcing the smoke up and into your mouth. 

Want to get the most ridiculous hits? Play around with adding extra water and slowing the speed that you lift the inner glass during your hit to maximize the clouds!

Compatibility Note:

While built for a flower combustion hit, we've had lots of fun experimenting with dry herb vaporizers in our gravity bongs. Just remember that gravity bongs have slower airflow than many vaporizers prefer so you may have to make some adjustments to get the best results. Typically we pack a bit tighter than normal and turn the heat up when using a gravity bong to maximize vapor. Our favorite dry herb vapes to use with a gravity bong include a Detachable Taroma 360 (with a long heat soak) and a Dynavap Hyperdyn (tip only).
