stretching the possibility of the human voice

Pentatonix redfines a cappella—and the possibilities of the human voice for that matter. Check out the video and keep this one fact in mind: there are absolutely no instruments used in the making of this music (apart from the human voice, that is).

leidenfronst and the water maze

I caught this little gem on NPR’s Science Friday. It describes the concept of the Leidenfrost Effect whereby droplets of water hover on a thin layer of steam when placed on a surface heated to optimum temperatures. A group of creative undergraduate scientists discovered that with just the right texturing of the surface, the droplet can be made to climb stairs and, in fact, move in prescribed directions when moving over heated blocks with different textures. Hence, the Leidenfrost water maze. The effect is quite beautiful.

some typhoons lift you up

I’m lovin’ NPR’s Tiny Desk Concerts. It’s a great place for me to discover new music and to take in a 15-minute concert from the comfort of my desk whenever the mood strikes. Most recently, I enjoyed a three-song set from Portland, Oregon’s Typhoon. This 12-person powerhouse barely fit behind the tiny desk, but the sound carried me up and away.
