Exploratorium Senior Scientist Paul Doherty explains a double rainbow sighting at Burning Man 2010! What is indigo anyway? Staff physicist Paul Doherty tells the story behind ROYGBIV, and how he'd like to change that standard palette.
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.
Exploratorium staff physicist Thomas Humphrey explains what temperature and color have to do with one another. Most things won't burn on Mars—after all, the main ingredient in the Martian atmosphere, carbon dioxide, is used in fire extinguishers on earth. So how would one create fire without oxygen? Use metal!This slow motion footage shows magnesium burning within a block of dry ice.
A detailed demonstration of how to do the Color Chromatography activity, which lets you see the colors hidden in black ink. Includes a discussion of materials needed. An introduction to an activity that lets you discover the secret colors hidden in black ink. With a paper towel, a black marker, and a cup of water, create a rainbow of colors while exploring capillary action and chromatography. Explore the science behind this activity, including capillary action (how the water moves up the paper) and chromatography, or how different elements of the ink are carried along at different rates, allowing you to see that black ink is actually made up of many different colors. Staff Neuroscientist Richard Brown demonstrates that the Giant Mirror reflects infrared radiation as well as visible light.
