Now that we’ve survived the firenadoes, it’s time to control the flames for ourselves. And what better way than making fires dance, using a contraption known as a 2D Rubens Tube?

Because the amount of gas changes around the tube, the heights of the various flames oscillate making a pretty trippy display. And yes, we can best describe this as arsonist porn. Know more.
