Britain's New Invention Could Replace Printers Forever

Okay, so somewhere in Britain right now, there's a lab that figured out how to make a piece of paper forget everything printed on it. Not shred it. Not recycle it. Forget it — like wiping a whiteboard clean, except it works on regular printer paper with regular toner, no special ink, no special cartridge, nothing you'd even notice was different. And by the time I get to the middle of this video, I'm gonna tell you exactly how they pulled it off, because honestly, the mechanism is way simpler than you'd expect, and it might just be the thing that finally kills one of the most wasteful machines still sitting in every office on the planet.
