Make your own glowy orb
Make magazine shows you how to do it with a styrofoam ball and some electronics.
Sometimes, the techy arts-and-crafts picks that Make magazine's blog talks about are just too cool to pass up. I never did get around to obtaining a paint mixer to build a , but now I'm inspired to build myself a GloGlobe, which Make recently featured. It's constructed out of a Styrofoam ball with a battery, an LED, and some electronic bits shoved inside. The blog recommends it for Dune junkies who want to create their own Holtzman effect, but personally, I think they would make amazing party decorations. Too bad I didn't know about this before New Year's Eve!
Of course, I'd have to learn how to tweak meticulously with small pieces of electronic equipment, first.
GloGlobes would also be a great way to scare co-Craver Mike Yamamoto. As he's very willing to admit,scare him almost as much as does.
