Frosted glass is cool, but it seems to defeat the actual purpose of glass, which is seeing the things behind it. It turns out you can make frosted glass truly transparent with just a bit of tape.
Frosted glass is essentially glass with many tiny imperfections. As a result, sticking some Scotch or other clear tape over it will fill in those imperfections, while keeping the outer surface of the tape flat—thus letting all the light shine through instead of refracting off all those imperfections. Whether you're just annoyed that you can't see past the frosted glass by your desk or you have more nefarious intentions (spying?), it's a quick and handy way to get around frosted glass' annoying opacity. Check out the video above to see it in action.
