Water can do some trippy things, man. If you take a glass of water and slide it in front of a pattern, the refraction of light in water basically screws with those patterns and makes it appear as something else entirely. The distortion is really crazy to see because black and white squares turn into alternating white…
Here's a fun old trick anyone can do: draw arrows on a piece of paper, put a glass in front of those arrows and pour water into the glass. Watch as the arrows you drew magically change directions right before your eyes. Refraction is a mind bending thing.
It's easier than you think to create these weirdly beautiful colorscapes.
Everyone knows you don't get pictures of rainbows this beautiful, without sacrificing a few leprechauns. Like, seriously, at least 100 of the little guys.
Refraction is a mind-bending idea. Light passes through a clear object, and it comes out the other side, inverted. The Shooting Challenge results that follow are must-sees, the winner is astounding and...well...we busted a cheater, too.
We've all seen reflection used in photography—like when a lake doubles as a mirror to the sky. For this week's Shooting Challenge, we're going a step more complicated and using the principles of refraction.
While some work toward an invisibility cloak, University of Illinois professor Nicholas Fang is taking steps to create a similar material, only for sound, that could, for example, make ships invisible to SONAR. To successfully do this, of course, requires we break the laws of physics. But, you know, whatever.
