New "unplugged" exhibit at Science City: all about energy. Huge hamster wheel creating energy to power a sign. G was the only one strong enough to really get it going, and she'd poop out before it was half lit. Lots of touch screens for learning about the forms of energy; a couple stationary bicycles for lighting bulbs; huge electromagnetic wheel to spin and light diodes.
Kinderlab is one of our favorites because of the huge blocks. Also spent some time digging in a pit looking for fossils.
