The Velocity of Light
The speed of light is extremely rapid: extremely rapid. And yet, if you are exceptionally fortunate, you can technically record light in motion on camera. This guy installed an LED light in his faucet and photographed it as it changed colors, resulting in this.
When for why he desired an LED light in his faucet, we presume he simply desired that his water appear very cool as he cranked the handle. And, to be honest, the more we think about it, the more awesome it seems. Perhaps we should give that a try?
