AUSTIN (KXAN) — Science heats up with this physics lesson as flames dance to the beat of music.
Starting out with the Rubens’ tube concept, this 2-D plane takes it to the next level with the “Pyro Board.” A Rubens’ tube is also known as a flame tub — an antique physics apparatus for demonstrating acoustic standing waves in a tube and the relationship between sound waves and sound pressure.
There’s a man who goes around Denmark showing kids all about physics, using this Pyro Board as a neat demonstration of what pressure variations can do.
The sound waves affect the pressure variations, impacting the flow rate of flammable gas from the holes in the board, according to the video’s post. Therefore, the height and color of the flames are changed.
This is even more awesome to watch when it’s synced to music — the beat bursting into balls and waves of flames.
