Liberty Science Center
Time Out says
The Liberty Science Center, which was totally refurbished in 2007 succeeds beautifully in its stated aim to reinvent the science-museum-going experience. An interactive, heat-sensitive "cave painting" allows tykes to add their handprints to the mural like real Cro-Mags. Then there's the giant blue nose that sneezes spray at visitors. And let's not forget the I-beam, suspended 18 feet in the air, which lets kids "walk the steel" just like a construction worker building a skyscraper (with a safety harness, of course).
