This takes approximately 15 minutes, creating a charge on the capacitor that could be lethal. The capacitor is then discharged through a 12" length of 30 gauge bare iron wire.</p><p>When the high voltage current flows though high resistance wire, the bonds between iron molecules are shattered, resulting in a loud bang, a shower of sparks, and a cascade of wispy filaments floating through the air.</p><p>Not all of the charge on the capacitor is disharged through the wire, so a shorting bar must be used to release the remaining charge. </p> 121 tag:techtv.mit.edu,:Array/184965040 2007-07-12 19:04:35 -0400 eng-youth-thoughts Get some views from some MIT students on what advice they would give someone in high school. 100 tag:techtv.mit.edu,:Array/184941180 2009-05-27 11:18:37 -0400 MIT Department of Physics Technical Services Group Rubbing the rim of a wine glass with a wet finger will cause it to resonate at its resonant frequency. The glass is placed in front of a speaker playing a sine wave, created by the function generator, of this same frequency. When the amplitude is turned up, we can see by shining a strobe light at the glass that this resonant frequency causes it to oscillate. When the glass becomes too stressed, it will shatter, which we see very clearly on high speed video. <br><br> A few things to note: The scrolling effect seen in the strobe light footage is caused by interference between the strobe light frequency and the video camera frame rate. Also, the real oscillations of the glass are much faster than they appear in the strobe footage. Setting the frequency of the strobe light can make them appear much slower so that we can see the oscillations in real time without the help of high speed video. <br><br> We would like to thank Dr. Jim Bales of the MIT Edgerton Center for helping us with the high speed video recording, and for the use of the equipment. The high speed camera used here is a Phantom v7.1, donated by the manufacturer Vision Research, Inc. 154 tag:techtv.mit.edu,:Array/191760240 2009-06-08 10:44:25 -0400 Lemelson-MIT Program Cardboard, lots of duct tape and four hours to get creative. Using "wind" power, high school students from across the US build devices to lift a garbage can to the ceiling of the Boston Museum of Science during the Lemelson-MIT Program's EurekaFest 2008!

In the cloud chamber, these particles ionize air molecules, creating delicate cloud trails by condensing supersaturated alcohol vapor. This is similar to the way condensation trails are formed in the sky behind airplanes. <br><br> This is about as close as you'll ever get to seeing subatomic particles with your own eyes... 157 tag:techtv.mit.edu,:Array/190201160 2009-06-30 15:04:16 -0400 Center for Advanced Visual Studies Visiting artist and writer David Robbins will talk about “high entertainment.” A practice for the future that combines the critical capacity of fine art with the pleasures and reach of show business, “high entertainment” could be what you are already making. Robbins’s objects, images, and writing reflect on spectacle and the position of the artist in the visual system, and suggest possibilities for a new relationship between art and the entertainment industry. + David Robbins has had over three dozen solo exhibitions in the United States and Europe and is the author of five books, most recently The Velvet Grind: Essays, Interviews, Satires (1983-2005) and a novella, The Ice Cream Social (1998, re-issued in 2004). He is currently writing an alternative history of twentieth century comedy. 6349 tag:techtv.mit.edu,:Array/189504360 2009-08-31 11:43:07 -0400 MIT Alumni Association Three MIT alumni share their best practices in STEM teaching and learning both inside and outside the classroom.
