The tagline of this site is "Puzzles: Can you believe it?" And your answer will almost certainly be "Absolutely not!" once you get a look at the number of IQ tests, optical illusions, droodles (that's a combo doodle/riddle) and other creative games, curiosities, crafts and whirligigs. Archimedes, that Sicilian wonder who, among many other discoveries, figured out the weight of a body in water, must have had quite a busy laboratory in which he conducted his experiments. This virtual lab borrows the empirical spirit and creative curiosity that Archimedes brought to his work and invites visitors to explore with the same expectations for mind-blowing discovery. Perfect for kids, this hands-on wonderland puts young scientists in the driver's seat for endless learning and fun. -- SCIENTIFIC AMERICAN.com
