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
