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) Cory 25

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.

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.
