Soon after the Nintendo Wiis release, hackers immediately began uncovering ways to use its unique motion-sensing controller to interface with other things—PCs, musical instruments, you name it. But Tom Tlalim, an Israeli-born composer who now lives in the Netherlands, may have outdone them all: His full-body, eight-piece suit of Wiimotes interfaces fully with custom software to turn his entire body into an electronic instrument that responds to his every motion. In his suit, Tlalim doesnt play songs. He dances them.

Usually our 5-Minute Projects involve soldering and LED lights and other such electronic accoutrements, but this week we decided to skip the fancy stuff in favor of an old-school science project: making rheopectic slime from Borax and glue. This is a pretty safe experiment even for kids--just make sure to do it with parental supervision and keep the Borax, slime, and any fingers that have been touching the aforementioned items out of eyes, noses and mouths.

Last night at approximately 10:26 EST, after a long buildup of preparations, the Navy took the controversial step of shooting down a dead U.S. reconnaissance satellite from its low-Earth orbit. The satellite, which is about the size of a school bus, was destroyed to prevent a potentially hazardous impact with Earth, the military has said. It was moving faster than 17,000 mph at an altitude of 133 nautical miles above the Pacific when a modified SM-3 anti-ballistic missile launched from the USS Lake Erie, a Ticonderoga-class AEGIS missile cruiser, reportedly made impact.

We first saw the Livescribe Pulse "smartpen" in action at the DEMO conference last month, but today CEO Jim Marggraff stopped by to give us a closer look.

When you use the Pulse to write on paper printed with a special microdot pattern, it recognizes its exact relative location on the page and captures a digital file of your pen strokes (complete with full character and word recognition) along with audio. The pen can also then interact with written words on the page in many interesting ways, including live audio translations into multiple languages of any word you tap.

There are many unusual things to see around Newton Falls, Ohio—the Wal-Mart with hitching posts for Amish buggies, the Army base with helicopters and tanks proudly arranged on hills—but I was here for the most unusual thing of all: the local Dynamitron. I was here to make frozen lightning.

As any informed PopSci reader will know, the iPhone is definitely a game-changing piece of hardware, but it's not without its problems. Chief among those nagging little imperfections, for me, was the recessed headphone hack that rejected any headphones but Apple's trademark gleaming white buds. Apple's 'phones aren't that bad, but my Shure in-ear pair is better for blocking out noise on the subway (and my Grado SR60s are better for listening at home). Thankfully, an easy solution to this problem is just a trip to the local Radioshack away.

The U.S. State Department is not happy about yesterdays celebratory announcement and rocket launch in Iran. Revealing the opening of a new space center, Iran also launched a rocket, the Explorer-1, towards the heavensalthough whether it actually got to space is up for debate, since Irans first domestically built rocket, sent skyward last year, may have failed to reach orbit. Iran says this effort is all about scientific and technological development, but the international community is clearly concerned that the country isnt just envisioning using these rockets to launch satellites.

Um, wow. This video comes from a test firing of the Navys Elecromagnetic Railgun (EMRG), which was carried out yesterday at the Naval Surface Warfare Center in Dahlgren, Virginia. The gun—which generates a powerful electromagnetic field to hurl projectiles at extremely high speeds—is rated at 32 megajoules, but the railgun engineers have to work up to that number slowly: this test was designed to reach a record-setting muzzle energy rating of 10 MJ. (The actual number turned out to be 10.64 MJ, according to Collin Babb with the Office of Naval Research.)

One big question this video begs is, what causes the giant fireball?

To a chemist, burning means the rapid combination of a fuel with oxygen, called oxidation. You might say, for instance, “Oh, no, we didn’t have a fire at the nuclear power plant, we just had a ‘rapid oxidation event,’ ” a phrase that won officials at Three Mile Island the Doublespeak Award in 1979.

Ah, the alluring glow of the LED light. Whether you're looking to create a bit of romantic (albeit extremely geeky) ambiance, or you just want to have some extra emergency lighting around the house, a set of mini LED candles is a great thing to have. They also happen to be quick, easy, and cheap to make yourself. In this video, executive editor Mike Haney demonstrates how to do it.

Too busy to drive? Let the car take the wheel. PopSci recently went for a ride in the Chevy Boss, winner of the 2007 Darpa Urban Challenge. With tricked-out GPS, sonar, laser guidance and a stack of computers, this 2007 Chevy Tahoe SUV can navigate an urban setting, weave around obstacles, and even negotiate intersections with other cars. GM expects the technology to be affordable, and less obtrusive, in about a decade.

Talk about thirsty. The water-gulping feat in the trick shown here doesn't quite demonstrate Kobayashi-level skill, but it's still a shock to watch. In a tremendously un-scientific test, we determined that it would normally take about 12 seconds for the water to empty out of a similarly-sized bottle held upside down. This drinking champion does it in under five.

A screwdriver, fan and a whole lotta spray-on plastic make for one sexy data storage device. In this week's edition, web editor Megan Miller demonstrates a foolproof technique for tricking out your flash drive by stripping it bare.
