"Levitating _____" is a classic Kickstarter formula. There are levitating clocks, levitating lids, levitating turntables, levitating speakers, levitating incense holders, levitating light bulbs, and so many levitating plants. None of these are strictly useful, but they all look amazing and impossible and, briefly, they look like they would look good in your living room and not at all silly and unnecessary after a few days. The last one, and one of my favorites yet, is a machine that levita drops of water called LeviZen.
A levitation clock, a turntable and a speaker – and to a lesser extent a levitation support, a bulb and an incense holder – are at least somewhat useful for object levitation, but the levitating water drip machine is not more than a visual touch. There is not a hint of practical use, and it is hard to imagine that he will use it for more than a few moments throughout his life to impress or confuse a friend.
It seems (and essentially is) a strange piece of audio equipment
Simplistyk, the company behind LeviZen, seems to be perfectly aware of this and has apparently spent as much time designing a retro look with style for the machine as it has done in the development of relatively basic technology in itself. The LeviZen looks like a dark piece of audio equipment from the 70s, with a walnut box, brushed aluminum plates, a large metal knob and three striking metal buttons. He would put his control box on display somewhere, even if it was not connected to anything.
It is appropriate that the LeviZen looks like a strange piece of audio equipment because it is essentially one. To make the water levitate, it throws opposite ultrasonic waves back and forth so that they combine into a standing wave, which has points that remain perfectly still. By placing water at those points (known as "nodes"), droplets can float in the air because they are trapped between equal and stable forces. The sound is ultrasonic, so you can not hear it, even if your pets do, so that's something to take care of.
Simplistyk has already raised more than $ 50,000 from more than 250 sponsors on Kickstarter, which is well above its $ 15,000 goal. As always with Kickstarter, be careful when you decide to back them up, as things can go wrong. Simplistyk has sent a product before, an elegant top / gyro (but not levitating), after running a successful Kickstarter, however, the product seems to have been sent two years late. Also, keep in mind that the LeviZen has no practical use.
