GRAV - Medium Gravitron

The bong that launched a legacy, the GRAV Gravitron gravity bong! To experience the legendary gravity bong, the rig functions by first adding water to the glass base, lighting a bowl, and slowly pulling the top glass, as the suction draws smoke from the bowl filling the chamber with smoke! Once it's full, press back down. The water refills the center chamber and pushes the smoke back out the mouthpiece, much, much faster. Powerful hits in this unique design from GRAV Labs!
