Videos: What Are Zen Magnets and Why Is the Federal Government Banning Them?

This week's cover story, "Magnetic Attraction," tells the tale of Zen Magnets, a Denver company founded in 2009 by University of Colorado grad Shihan Qu. The company sells -- you guessed it -- magnets. But these aren't just any magnets. They're tiny, high-powered spherical magnets that can be used to build everything from complex geometric shapes (octahedron cuboctahedron honeycomb, anyone?) to replicas of Super Mario Bros. characters. And last month, they were banned by the federal government.

Below, we've compiled several videos that help tell the story of Zen Magnets.
