How to Build: A simple washtub bass. Some variations (on a crazily made webpage). A cookie tin banjo. (Previously) A cigar box guitar, and a cigar box ukulele. A fancy cigar box uke. (Kathy Marsushita's whole amateur luthier projects page is worth checking out, as is this gallery of cool cigar box ukes.)

Let's build...Blarney Castle, a model building to test on an earthquake simulator, Thoreau's cabin, a stirling engine, the NYC transit system, a model bridge, Galileo spacecraft, the Mars Polar Lander, a flying Martin XB-51, Aliens universe papercraft, a train layout under your bed, a stereoscope, a flying saucer. Or we could let The Swell Maps do it: Let's Build a Car. And don't forget, "Your country needs scale model planes for the emergency."

Foudre en Boule avec des micro-ondes (Making ball lightning in your microwave). Complete with movies and audio spectrum analyses. From the Plasma Research website. Also: how to build a stable plasmoid in your microwave; simple ball lightning generation in your microwave; and, last but certainly not least, how to build yourself a glow discharge plasma panel. "This panel is not able to generate some thrusting effects, but you will be able to explore some OAUGDP properties like the air drag reduction effect and to test the EM Cloacking effect."
