So this experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First add sand to the plate then begin playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand "falls" into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.

We check in with the team at Liquipel, a company that impressed us last year with its water-resistent nano-coating for smartphones. Dunking an iPhone into a tub of water and watching it still work perfectly is still amazing and something our brains struggle to comprehend.

Being able to calculate the failure front velocity of a Prince Rupert's drop is a pretty big deal. For years this was a scientific mystery. High speed camera technology is only recently fast enough to provide data like this. Thanks to Vision Research for letting me use the V1610 to try to unravel this mystery for the public in general.
