When 5 of my little cousins came to visit me a few years ago (ages 5-11), I planned to take them to this Museum on Sunday when admission is free for several hours. I thought that was really nifty, for them to be so generous. At first, the kids groaned when I told them I was taking them to a museum. When we got there, the kids couldn't have been happier with the interactive displays and neat toys. There was plenty of science in the mix to make it a real educational experience. I had to pry them away from the place.
