Here's a site that will keep you busy for a while.
"Show Off: How to Do Absolutely Everything. One Step at a Time" is a new book that has all kinds of neat little science (or at least science-like) experiments for young people, but most of these ideas will entertain adults, too. The Web site allows you to pull a lever and get a random experiment or mini-project to keep yourself entertained for a little while.
