Levitating Waters
The device featured in this video is quite interesting. Depending on which setting is chosen, water droplets appear to be stationary, falling, or moving in an upward direction. In reality, the water is falling down as a steady stream exactly as you would expect it to behave. Inside the box, however, there are a series of strobe lights. The frequency of the strobes flashing makes the water appear to behave in different ways. If the strobe lights flash at a specific rate, then the droplets appear to be hovering. By making adjustments to the timing of the strobe lights, the drops can be made to have the appearance of moving up or down. I wouldn’t mind having one of these in my office.
