Pyro Board Breathes Fiery Life Into Music

Stand back, things are about to get heated.

A team of Danish physics demonstrators created this Pyro Board, which can visually represent sound waves on a 2D plane with fire.

The concept of the board stems from a Rubens' tube, which is an antique physics tools used to visually demonstrate what a standing wave looks like. This wave that stands in a constant stationary position consists of nodes, or low points, and anti-nodes, or high points.

The waves are represented on the perforated tube when flammable gas is pumped through one end of the tube and a sound wave through the other via a speaker. Read more...
