Things seen at the speed of sound

The ‘colour sculptures’ in following video were created by stretching a balloon over a speaker to form a membrane. A few drops of paint were then placed in the centre of the balloon and a single sharp note was played through the speaker, causing the paint to erupt for just a fraction of a second. Just a few centimetres high, the sculptures are ordinarily invisible to the human eye. However, when filmed in HD with macro lenses at 5,400 frames per second, the physical sound wave is captured in intricate detail.

This video, and still photo advertising, is part of an advertising campaign for the PIXMA colour printer in the UK. [Thanks to Duncan McLeod of the Inspiration Room for pointing me towards this - he's also 'unearthed' of a number of other videos we've put on this blog.]
