If you’ve ever worked in a cubicle surrounded by frosted glass partitions, you may’ve seen this trick before – but for those of you who haven’t, come in and let us surprise you with this magic trick.
As OMG-Facts explains:
“The surface of frosted glass is etched so that when it is struck by light, the light is scattered and any images viewed through the glass become distorted and largely indistinguishable. Placing tape upon the surface of the glass fills in its irregularities and allows the light to pass through with much less scattering!”
Maybe so, but- hey look! I just saw my co-worker pick his nose! [YouTube via Core77 via Wired]
