We can't tell you how many times a day
we wish we could flip a switch and turn a wall on or off, and it sounds like at least some scientists at the Imperial
College in London and the University of Neuchatel are on their way to creating just that. Or at least that's what
they'd have us believe; they won't really discuss their discoveries too openly, but they claim to have created crystals
invisible to the human eye, which could theoretically imbue building materials and make things (like walls) invisible.
We're a little skeptical, so we encourage said boffins to um, show us. That is, if they can find where they placed
their fantastic invisible material.
