It's free. They work on donations.
Yeah, right now it's donations only. It's a small, homegrown operation and the owners are the nicest people. If you don't feel convicted to donate after visiting, you might not have a soul. :-) It's a great place though, my family and I have been quite a few times and the kids get to be so hands on and touch everything... They're in heaven. Highly recommend.
