What do you get if you take some magnets, superconductors, and liquid nitrogen, and a slow-mo camera to film them with? This kind of magical footage is what.

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.

If you play around with an ultrasound field for long enough, you can set up standing waves that allow you to levitate water drops in mid-air—but that’s only where the fun starts.

Scientists use sound waves to lift and move objects, make cup of joe mid-air
Posted in: Today's Chili
Levitating objects with sound waves isn’t anything new, but a team from Switzerland has taken it to the next level by rotating and moving objects as they float. In fact, the researchers were able to manipulate a number of objects mid-air, including water droplets, inserting DNA into cells and mixing up a little instant coffee. If you’re wondering how intense sound waves need to be to get things moving (at this level, at least) then 160 decibels is the starting point. If that sounds ear-splittingly loud, that’s because it is. But, by using frequencies typically out of the human audible range (24 kHz), no ears were at risk. The movement itself is controlled by a grid of sound-emitting squares. Once the object was in the air, it could be moved around by lowering the volume on one grid point, and increasing it on the next. For now, the science is only able to lift tiny objects, but the same team claims that it’ll will soon show similar work using steel balls. Could we use this to get our (sonic) hoverboard? We’re not calling that just yet.

Though this prank video is an obvious attempt at force inducing viral-ity by Pepsi Max, it’s still a pretty fun watch. The magician Dynamo tricks people into thinking he can levitate by ‘magically’ following a bus around as it moves across London. Watch people freak out when they see him float.

Levitating Wireless Candelabra Makes For an Amazing Thanksgiving Centerpiece [Video]
Posted in: Today's Chili
It’s all explainable via science, but if you replace your typical cornucopia centerpiece with this floating steel plate supporting a glowing wireless candelabra, your dinner guests will be too blown away to notice your dry turkey and lumpy gravy. More »

The demonstration in the video may seem like MAGIC! but it’s real: scientists at the U.S. Department of Energy’s Argonne National Laboratory are employing a levitation machine that uses sound waves to make liquids float and create “more effective pharmaceuticals with fewer side effects.” More »

How Many Engineering Students Does It Take To Create a Levitating Glowing Light Bulb? [Video]
Posted in: Today's Chili
Just one, as Chris Reigler, an electrical engineering student from the University of Queensland in Australia, discovered. His floating LevLight project could one day revolutionize the way we change burnt out light bulbs, and make thousands of “how many X does it take to change a light bulb?” jokes completely moot.

How many engineering students does it take to build a floating light bulb? Just one. University of Queensland student Chris Rieger combined magnetic levitation and wireless power transfer like peanut butter and jelly to create a fancy floating sandwich. And by sandwich I mean light bulb.
Watch the magic happen in the video below:
Rieger says he’s working on a much better version of the bulb, one that will have a built-in dimmer and height control. Drop a comment on YouTube if you’re interested in buying that improved model to help Rieger decide if it’s worth making multiple units.
