The Ultimate Way To Visualise Sound

You might think the trippy animated visualisations in your media player are the best way to see your music, but astronaut Don Pettit has found a better way. All it requires is a small set of speakers, a blob of water and a space station 400km above the Earth.

On the planet's surface, the water would simply flatten out due to gravity, and the soundwaves would look like boring old ripples on the surface of a pond. But on the space station, where gravity's pull is almost non-existant, the water holds its shape as a half-sphere that gets deformed in 3D as the soundwaves emanate from the speaker in all directions. It's utterly mesmerising, and we can't think of a better reason for aspiring to be an astronaut than this simple experiment. [YouTube via The Verge]
