Hasta La Gadget!

Behold witchcraft! Some crazy mages who call themselves scientists are making stuff levitate using ultrasound waves. Check out the video below. It demonstrates three-dimensional, mid-air acoustic manipulation, aka levitation. Aka witchcraft!

Scientists in Japan are using this technique to suspend small objects in the air with ultrasound waves and they have created an array of wave emitters capable of levitating objects in any direction. Why do these wizards boast of their magic so openly, unafraid of burning at the stake? I have watched the video. I know magic when I see it! I am holding my pitchfork right now!

Seriously, this video just makes my brain hurt. It is amazing. Check out all of the details on their website. This amazing science is the work of professors Yoichi Ochiai, Takayuki Hoshi, and Jun Rekimoto. They have powerful magics indeed.

In 1960, scientists did one of those experiments that just aren’t allowed anymore. For the sake of science, they blew up three 3oo-lb anti-submarine bombs off the coast of Australia. A listening station 10,000 miles away in Bermuda—on the exact other side of the planet—waited. And waited. And, about three and a half hours later, they saw the blip that confirmed their hypothesis: Yes, sound in the ocean really can travel across the world.

With 28 speakers blasting around 125 watts, the original Wall of Sound made for an obnoxious home stereo system—let alone an iPod dock. But its creators have returned with a bigger and better solution: the Wall of Sound 2.0 that adds an extra 16 speakers, bringing the total to 44 (in addition to a pair of subs) for more decibels and bass than an iPhone dock ever needs.
