Exploratorium Senior Scientist Paul Doherty explains a double rainbow sighting at Burning Man 2010! In June, 2010, the Exploratorium will launch it's newest exhibition, Geometry Playground. Check out this teaser clip and come back for more on June 25th, 2010. Newton wasn’t really ready to believe that light was a wave, and so he didn’t see what was in front of his eyes. Staff physicist Paul Doherty tells how to do the same experiment that Newton did back in the 1650s to see the wave nature of light.

Doc--not just an inventor and a video editor but a yo-yo champion as well--will also demonstrate some yo-yo tricks.
Inventors Windell Oskay and Lenore Edman demonstrate the CandyFab 4000, a printer that creates 3D sculpture by stacking 2D images made of sugar. Drawing from disciplines as varied as circuit hacking and sewing, the sugar printer is only one of Oskay and Edman's many projects, which include an interactive dining table and hard-drive wind chimes.
