What we're seeing here are two solid-state Tesla Coils, each running in the 41 kHz range, performing a little concert thanks to some ingenious electrical work. The coils, which have been nicknamed the Zeusaphone, were developed by Tesla enthusiasts Jeff Larson and Steve Ward.

On his site, Larson explains that a particular version of this type of coil can be good for audio modulation because it produces several hundred sparks per second. The apparently continuous crack of light we see is actually a series of brief sparks. Larson and Ward figured out a way to modulate this frequency digitally, and get the sparks to crank out the sound waves or musical notes they want.

This concert features "Dance of the Sugarplum Fairies," but they've also done the theme from Super Mario Brothers and others. In terms of audio quality it doesn't quite measure up, but when you're talking pure spectacle, this has to be tops. You wonder if Tesla himself would be proud.—Gregory Mone

Even Michael Jordan would have to be impressed with this dunk. The athlete (?) in this very popular video clip apparently breaks the world-record for a trampoline-aided, long-distance dunk, soaring more than 20 feet before slamming it through. That's outside the college three-point line, MJ.

The secret to his success, according to physicist Len Fisher, an Ig Nobel winner who runs a website focused on the science of everyday life, is the leap forward towards the front of the trampoline, right before he flies to the hoop. He's not merely closing the gap here. In the middle of the trampoline, he's stretching all the springs on the outside equally, but once he moves to the edge, he really only stretches the springs closest to him. "The closer to the edge," Fisher says, "the more effective the recoil is going to be." And since he tilts his body forward, that recoil throws him horizontally.

The amazing thing, Fisher adds, is that he doesn't slip when he pulls off this switch between vertical and horizontal motion. You'd need incredibly high friction between your feet and the trampoline. Fisher wonders if he had some sort of resin that gave him a better grip. And the look of tension on the face of that guy with the glasses? Sorry, we can't explain that one. But it might just be the highlight of the whole clip.—Gregory Mone

Apparently classic cars aren't enough of a draw anymore. The Mercedes-Benz Museum in Stuttgart, Germany turned its smoke ventilation system into a spectacle, generating what the Guinness World Records organization is calling the world's largest artificial tornado. (See the November issue of Popular Science for an article about an engineer who thinks these man-made vortexes could be used to generate electricity.)

Though towering, the twister probably isn't dangerous. It's not going to suck up any bystanders, or cars. To create the effect, the museum's designers set up a disco smoke machine, then activated a set of 144 nozzles on the ceiling of the building's enormous atrium. The ventilation system, designed for emergencies, sucks the disco smoke up from below. To produce a spinning vortex, however, they blew air in from the sides, forcing the smoke to swirl.

The process took seven minutes, but the result, seen here, certainly looks capable of drawing crowds. Or making them run for their lives.—Gregory Mone

This little party trick is guaranteed to impress, and you don't need any special materials, just a decent freezer and a bottle of beer. Emory University physicist Sidney Perkowitz, the author of the forthcoming book Hollywood Science, says the phenomenon at work here is most likely supercooling - a process by which water can remain in a liquid state below its freezing point. It's a delicate balance, though, as the water will turn to ice given the slightest shock.

If supercooling is the culprit, the hidden scientist in this video most likely left the bottle in the freezer long enough for it to drop down below the freezing point - some other sites recommend about 30 minutes. Next, the shock of slamming the bottle on the table jolts the beer, and this added energy forces it to crystallize into ice.

Of course, it's hard to say for sure what's happening in this clip, and the many other frozen beer related videos posted on YouTube, because we don't have all the information. The best way to test the idea would be to try it yourself. I'd do the same, but I don't believe in waste.—Gregory Mone
