Water Does Some Really Weird Shit to Things

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 whiteâ€¦

Why A Volcanic Eruption In Chile Is Turning Brazilâ€™s Sky Purple

This is what a sunset in Rio de Janeiro looks like right now, and itâ€™s all thanks to that volcano erupting in Chile last week. Calbuco spewed 7,420 million cubic feet of ash into the atmosphere, turning nearby regions into a â€śgrey desertâ€ť and altering weather thousands of miles away.

Watch an arrow change directions in this simple water optical illusion

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.

Refractographs are eye candy brought to you by physics

It's easier than you think to create these weirdly beautiful colorscapes.

Many leprechauns died to bring us this gorgeous picture of a rainbow waterfall

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.

72 Ravishing Refractions

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.

Shooting Challenge: Spherical Refraction

We've all seen reflection used in photographyâ€”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.

Scientists Nearing Creation of Sound Cloak, Breaking Laws of Physics

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.
