Unwise Microwave Experiment
Posted by: wbeaty
Video duration: 313 seconds
Beer bottle in a microwave oven. IT MELTS. No, it's not very safe. Not for kids!
That's my original oven from 1994, it's still working fine (but with paint a bit burned.) Whenever you see charred spots on your ceiling, you know that someone's been making plasma balls again.

Dry Ice: is it LETHALLY DANGEROUS?
Posted by: wbeaty
Video duration: 271 seconds
Between "Genuine danger" and "Raving Safety Paranoia" there must be some sensible middle ground. Dry ice is fun. Figure out a way to handle it safely.
Buy dry ice from suppliers listed in your yellow pages phone book for about $1 per pound. Or in Seattle, get it from QFC grocery, in the seafood section.

Fingernails Chalkboard Music
Posted by: wbeaty
Video duration: 101 seconds
No chalkboard needed: dry ice with warm metal pressed against it. We automated the process with a gearmotor slowly turning a mixing bowl. The two bowls make great sounding boards (the noise was LOUD.) Hosted by the folks at http://www.911media. org/, http://www.dorkbot.o rg/dorkbotsea/ monthly tech/art/DIY meetings.

PT 2: neodymium supermagnets, beads: amoebas
Posted by: wbeaty
Video duration: 124 seconds
Bought online from various suppliers. Small neo supermagnet spheres are COOL, especially if you have over fifty of 'em. See links to suppliers at bottom of http://amasci.com/sp heres/
I got these 8mm nickel-plate spheres from Mr. George, $0.35 each, http://supermagnetma n.net/ Chrome plate or gold are more expensive than nickel.
