Or can it? Look at this stack of books... How is it staying up? Is it glue? Velcro? Tractor beams? The secret is a simple and clever little device called the Hidden Bookshelf! An L-shaped wedge of metal holds your books up against the wall while a tiny clip holds the inside cover of the book up, giving your larger books the illusion of sticking to the wall as if by magic!
