Using fire to visualise sound waves

The Rubens tube, also known as a standing wave flame tube, is a physics apparatus that visually illustrates the connection between sound waves and sound pressure Flames along the tube's perforations respond to these pressure variations

This is a standing wave. It can also be visualized using sound waves and water (instead of fire). In this example, a 24 Hz sound wave captured at 24 fps creates the effect of the standing wave.

Physics is absolutely mind-blowing
