I went here for frys free weekend yay thanks frys and thanks to laura for telling me about it! I love this place best museum ever. I'm from San Francisco and I'd say this museum is a mix of the exploratorium and the academy of science. Place is amazing I'm for sure bringing my little brother here not so little brother that is he's 21! The place is soo boob.com!! I'm a nursing major and the found the anatomy and brain department amazing. I spent like 615644 hours there. The exhibits were so cool my favorites were this thing that slides over the body and does a scan over the body showing the parts letting you click on the screen while you glide the x-ray panel. Breath taking, I also loved the heart beat drums that went with your pulse, the digestive tract, and the surgery done on a manikin with a moving slideshow. I love this place!! Will be back def. an Arizona must see and gem! At an affordable 12 or 14.
