The Rubens tube, invented in 1905, is an acoustic experiment that makes sound waves visible by using fire. As sound passes through a gas-filled pipe with small holes on top, the varying pressure along the tube creates a fiery wave pattern that visually corresponds to the sound wave's nodes and antinodes.
