World's Lightest Material

The worlds lightest (ahem, least dense) material is about 100 times less dense than Styrofoam. That's just a little bit absurd. It consists of a microlattice of metallic tubes that are only about 100nm thick and the rest is just air. It is pretty tough, too. It can deform by 50% and still spring back to its original shape, unlike aerogels, which just shatter if you squeeze them too hard. I'm sure there will be many applications for this stuff, but super light electromagnetic shielding for is the first one that comes to mind.

Throwable Panoramic Ball Camera

Designed by Jonas Pfeil, this ball has 36 cell phone camera sensors that allow it to take pictures a full 360 degrees (or 4*pi steradians for the nerds out there) around the entirety of the sphere. Meaning from ground to sky and everything in between. Pretty impressive. Just throw it in the air and it has a built in accelerometer that it uses to sense the when it's at it's highest point and then snaps the picture. It makes for some pretty neat shots that software can mesh together so you can fly through the area you took a picture of. And it foam padded so you don't have to worry about dropping it.

Foam/Poppin' Possibilities

 This is quite the amazing video if you like patterns. My favorite part: thinking about the quantum length scale as a foam. Interesting because I had been thinking about this for the past couple of years and I'm glad to hear others may have thought of it too. My theory: Poppin' Possibilities. Infinite possibilities are arranged in a foam structure, and you can pop each of those possibility bubble just by thinking of that possibility. The world around you is the result of popping all other possibilities. Crazy? Probably...pop.
