One of the many things I love about being a parent is being able to do completely silly, childish things under the auspices of parenthood. Then I can safely say "No I didn't want to build a robot, make a waterspout, generate electricity, experiment with random motion, test my balance and reaction times, make music using vacuum force OR go see a cool movie about dolphins at the IMAX... I did it all for my daughter!"
Such a saint I am.
Seriously, this is a cool, fun place to spend a grey Cleveland winter's Staurday-- or frankly any other day. Tons of hands on exhibits. Very cool offerings at IMAX. If anyone asks, just point to some random kid and look saintly.
