“Nate True has developed yet another impressive hack using UV strobe lights, luminescent-dyed water, and a timer to create the illusion of water stopping in the air, slowing down the splashes into the pool beneath, and even travelling upward. You have to see it to believe it.”
Cool machine uses UV Leds to give a strobe effect to the fountain. fluorescein reagent powder is used to make the water fluorescent. A PIC micro-controller uses PWM to coordinate the liquid pump with the strobe Leds. By tweaking the electronics you can make the drops appear to be frozen in time or even move backwards. Nate has also started building a few fountains and selling them on eBay.
