The volcano was smoking, so we knocked and he gave us a couple of these Lava Flow Bongs. These great water bongs have everything you need for a great smoke sesh! Smoke travels through the 90 degree joint into the cone percolator for filtration, from there, the smoke travels up through the curved tube, preventing any flash back, and straight to you! Don't let this great percolating bong fool you, although it's got style, it delivers some huge lava flow rips! You can also use this bubbling bong as a dab rig, but you'll need your own banger.
