Welcome to the Age of 'Foomscrolling'

I remember the first time I saw the floaty rock. It was the middle of night, and I was facing the insomniac's dilemma: to reach for the phone or not. I reached and opened Twitter--this was two weeks ago; the new name hadn't yet sunk in--on the theory that a scroll through my feed might achieve some hypnotic effect, creating an opening for sleep to take hold. That's when I saw the blurry video. In it, a scrap of material, small and misshapen like a pencil's broken lead tip, hovers mystically above a thick wafer of polished metal.
