Hoverboards: they don't really hover, but they are one of the hottest gifts this holiday season -- both because people (inexplicably) like them, and because they literally burst into flames, sometimes.
To be quite serious, these things look lame, are technically illegal in many cities, and have caused some major injuries due to exploding parts. After reports of hoverboard-related fires in nine states over the past few weeks, most major airlines have placed the boards on the "no-fly" list, banning them from planes and airport terminals.
Now Amazon has joined the ranks of hover-haters. As first noted by Best Reviews, hoverboards have been pulled indefinitely from Amazon's labyrinthian online marketplace as of December 12. A statement made to The Verge by hoverboard makers Swagway (yes, unfortunately that is their real name) said "Amazon just sent out a notice to all 'hoverboard' sellers to 'provide documentation demonstrating that all hoverboards you list are compliant with applicable safety standards, including UN 38.3 (battery), UL 1642 (battery), and UL 60950-1 (charger).'"
