Science Teaching Tips:  Seeing the Light (Podcast)
Running Time:
00:04:52
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.

After Dark:  Fire and Ice: Magnesium Burning in Dry Ice (Clip)
Running Time:
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.

MAKE at the Exploratorium:  Making Your Own Kind of Music (Webcast)
Running Time:
00:23:54
Ezra Daly explains how he makes musical instruments out of car and motorcycle parts, then plays his Frankenbass, created from a Moto Guzzi motorcycle gas tank, a chrome tailpipe, and scrap mahogany. Next, Doc Popular (aka Brian Roberts) shows how he creates instruments by circuit-bending toys. Doc--not just an inventor and a video editor but a yo-yo champion as well--will also demonstrate some yo-yo tricks.

MAKE at the Exploratorium:  Like Making Candy: A 3D Sugar Printer with Windell Oskay and Lenore Edman (Webcast)
Running Time:
00:24:53
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.

MAKE at the Exploratorium:  Making BlinkyBugs with Ken Murphy (Webcast)
Running Time:
00:33:42
Tinkerer, programmer, and musician Ken Murphy shows how to build electromechanical "bugs" built from scavenged materials and powered with a single coin-cell battery. When the Blinkybug's wire antennae detect motion from air currents or vibrations, the bug comes to life, with its LED eyes blinking in rhythmic patterns.
