Backflow Burners

Backflow burners are so cool. The smoke flows and tumbles down the burner like a waterfall. Hypnotic and fun. How do they work? Well, you have to use backflow cones because they have the right shape with a hole in the base. And then you have to turn off all the fans because a breeze will really disrupt the flow. Light a cone, place it on top, and wait. By the time the cone burns halfway down you should have a pretty nice waterfall of smoke going. Trippy.
