A stimulating museum similar to (though much smaller than) the Exploratorium in San Francisco, the Lied features dozens of scientific exhibits that involve the viewer as a part of the demonstration. Don't be put off by the name: this is the sort of place that many adults would visit by themselves if they thought they could. Creative exhibits include a tin can telephone, which should entertain the kids for hours. Rumour has it that the museum will soon be moving to a new location, leaving behind the public library that surrounds it. Check before making a special trip.
