In this gem from 1990, we get a brief peek into the flourishing mind of German-born composer/sculptor Trimpin, a MacArthur "genius" award winner and the subject of a recent feature documentary. He chronicles his unique adventures through sound and music making, takes audience questions, and stages modified versions of his musical installations in front of the live audience. Exploratorium staff member Earl Stirling demonstrates the amazing "Pyrograph", an artwork refined over four years. Like a fiery version of the museum’s classic Drawing Board, Stirling’s "Pyrograph" swings a pendulum over a sandy cauldron, tracing out oscillating patterns in colorful fire. This mesmerizing piece evokes both the Foucault pendulum and Dante’s Inferno. This After Dark event featured a special installation of the Cubatron by Bay Area artist and engineer Mark Lottor. A visually stunning favorite of music and art festival audiences, the Cubatron is a 3–D light sculpture made from 8–x–8-foot modular cubes, each containing 1,000 individually programmable RGB LEDs. Viewed from any direction—even underneath—the Cubatron’s thousands of programmed pixels paint exquisite arrays of color that cascade in spectacularly dynamic patterns. Ken Murphy, creator of A History of the Sky— a time-lapse visualization that will span an entire year—talks about his project during the After Dark event, Resolution.
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 how to make your own simple speaker, which transmits sound from a radio or MP3 player and demonstrates the principles of electromagnetism and vibration. A detailed demonstration of how to make a cup speaker, including a discussion of materials needed. The science behind the Cup Speaker activity, including how electromagnets work, and how in this activity the magnet pushes the bottom of a cup back and forth, vibrating the air and creating sound. 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.
