The DaVinci Center

When we went to the Star Wars exhibit, we ended up getting a membership at the Franklin Institute because a full year of access cost less than the passes for just the day. Lucky for us, the DaVinci Center in Allentown is reciprocal with the Franklin. The kids and I spent some of our Easter break exploring the exhibits. Nicky loved the weather station, where he could be blue screened into various backgrounds. He also got brave enough to actually touch a starfish - and had me take a picture so that Daddy would believe him.
I'm still not sure why you need goggles to dig for fossils, but it sure looks scientific.
And the highlight for Kairi was seeing this little tropical frog, of course.
The DaVinci center is nowhere near as cool as the Franklin Institute, but hey, hard to argue with free!
