#2: Harry Potter and the Half-Blood Prince
Hermione always said, “When in doubt, go to the library.” We’re starting to think that perhaps that place was more fun than we ever realized. In Harry Potter and the Half-Blood Prince, we were wowed when we watched Hermione walk through the stacks, returning books without actually placing them back on the shelves!

Hermione only had to hold the book up near the shelf on which it belonged, and it would magically float into place. Only, they didn’t really float, of course. This picture shows us the secret behind getting those books onto their shelves: green-gloved figures grabbed them and put them in place. With greenscreen technology, the green hands are easily erased, making the books appear to float!
