How to ship a 6-inch neodymium magnet

Neodymium

Neodymium magnets can be so powerful as to be dangerous: you don't want two of them "spotting" one another when a fleshy fingertip is in the way of true love. So how do you ship a 6" one safely?

"So, is it really shielded?" asks YouTube's Braniac, chuckling to himself. "No."

The magnets featured in the video appear to be from magnetportal.de—what's a good place to buy irresponsible magnets in the U.S.? Read the rest

Hourglass full of magnetized "sand"

This $14, 100-second hourglass is filled with magnetized iron filings that form beautiful fans and other shapes as the sand drains into the bottom bulb. (via Canopy) Read the rest

Dogs poop in line with Earth's magnetic field

A paper in Frontiers in Zoology claims that dogs can sense the Earth's magnetic field, and preferentially align to it when pooping. (via Sean Bonner) Read the rest

Table made of a floating matrix of wooden blocks with embedded magnets

The Float Table uses a 3D matrix of wooden blocks with embedded strong magnets, tethered to one another, to made a piece of furniture that's awesomely wobbly, in an impractical, drinks-all-over-the-carpet way. Read the rest

Ultimate fidget-pen, made from rare-earth magnets

Polar is a pen made of 12 rare-earth magnets, which has blown way, way past its modest Kickstarter goal. It's the ultimate in fidget-gadgets, wildly reconfigurable, with the power to levitate magnetized rings along its axis. Wired's Kyle VanHemert calls it the Sistine Chapel of time wasting.

Gravity-defying levitating superconductor on a magnetic Möbius strip

Andy from the Royal Institution made a large, suspended Möbius strip out of rare-earth magnets, then cooled down an object until it became a superconductor, and set it levitating and running around the track. The result is amazing, plus Andy's explanation is cogent and fascinating. Plus, gravity-defying levitation!

50' chain of beads leaps and cavorts its way out of a jar

Steve Mould, Britain's Brightest's "science guy," showed that if you put coil a 50' chain of magnets in a jar and then casually toss out one end, the whole chain goes berzerk leaps and cavorts like an innocent colt on crystal meth, defying gravity and gravitas. In this video, Earth Unplugged gets Steve to explain what's really happening.
