The Pyro Board is touted as a 2D Rubens' tube. For those unfamiliar with that term, Wikipedia describes it as "an antique physics apparatus for demonstrating acoustic standing waves in a tube." But instead of using a tube, Sune Nielsen and the rest of his fire-loving friends in Aarhus, Denmark, developed the large Pyro Board in order to create even more patterns. Nielsen says, "We liked the Rubens' tube, but we thought when you put more fire it always gets better."
Derek Muller of the science video blog Veritasium visited his team to see the Pyro Board in person. Connected to a computer, the Pyro Board reacts in spectacular ways to a music piece by Kevin MacLeod counterintuitively titled 'Ice Flow.'
