Combined with the Derby events, here are my other ideas:
Louisville Slugger Museum This museum is a baseball history museum with a working factory. Here's their information: Admission:
$11 - Adults (13-59)
$10 - Seniors (60+)
$ 6 - Kids (6-12)
Kids 5 and younger are free. To see the bats being made, take a guided factory tour. Guided factory tours begin at 9:00 am and last about 25 minutes. The last factory tour of the day is one hour before closing. The website indicates that when the factory is not in full production, they will do bat making demonstrations. Everyone receives a miniature souvenir bat at the end of the tour!
Hours: Monday through Saturday 9:00-5:00
Sunday 11:00 -5:00

Another option for early Friday or Saturday or Sunday afternoon: The Speed Art Museum. http://www.speedmuseum.org/ They have an interactive children/family area, Art Sparks, where kids can make stuff with the really good art supplies that art people buy. Also something that turns your body into art on a giant psychedelic screen. Admission to Art Sparks is included with museum admission. Hours: Friday 10a-9p. Saturday 10a-5p. Sunday 12p-5p. After your kids are done painting with paints that you didn't have to clean up, you can walk around the museum and get a little cultured. If your kids aren't much into art museums, pick up a museum guide and have them navigate to the correct gallery and then be the first to spot the art that you describe from the guide. For kids too big to be so easily won over, you could also engage them by telling them about Van Gogh cutting off his ear. (the real story from abc news)
