By George Hart for the Museum of Mathematics Here’s a challenge: Make something cool from binder clips. It will be tough to beat this spherical construction by Yang Enqi. Using one handle, five clips of one color are linked cyclically into a pentagon. Using the other handle, twelve of these pentagons assemble like a dodecahedron […]
Mike “walks across America” from New York to San Francisco, part of some ad or something. Here’s a Google Map of his journey… He didn’t walk the entire distance but that’s not the interesting part, the behind the scenes video (above) has some neat tidbits on how you can make something like this too.
.all of a sudden, flying around in Google Earth really felt like flying, and exploring the ocean trenches was like piloting a submarine. When you splashed through the sea surface you cringed slightly, expecting to get wet. You could even command your own lander down to the Moon or Mars…With the Liquid Galaxy, we could fly through the Grand Canyon, leap into low-Earth orbit, and come back down to perch on the Great Pyramid of Giza without even breaking a sweat.
Have you ever been curious how a glow stick works or how they achieve all those wonderful colors? In this video from NurdRage you’ll learn what it takes to generate the chemical energy needed and how to harness it to create various colors in the spectrum.
When I was a teen, I was fascinated by alchemy — not so much the whole turning lead into gold part or trying to play God and create tiny little humans in a jar. I was really attracted to the labware, the furnaces, the study of the physical and natural world and its processes — […]
In response to this morning’s post about self-captioning POV ping pong paddles, a helpful commenter pointed me at this “action POV” gimmick from Flickr user zeni666.

Inspired by 19th Century Standhopes, Bristol artist Luke Jerram (of “Play me, I’m yours” fame) designed this elegant and inspired portrait projecting ring for is wife Shelina Nanji as a wedding ring. Working together with jeweler Tamrakar, Jerram created a ring that, in a darkened room, with a light source behind it, will project a series of portraits from a selection of miniature slides.
