Via MyBlogLog “hot in my community” list. Great. Luckily my house has asbestos (not metal) siding. Anyone selling kits or pre-made “throwies”?

LED Throwies are an inexpensive way to add color to any ferromagnetic surface in your neighborhood. A Throwie consists of a lithium battery, a 10mm diffused LED and a rare-earth magnet taped together. Throw it up high and in quantity to impress your friends and city officials.
