If you want guests to think you have some sort of magical powers, pick up the Invisible Bookend. Will they be curious as to why your magical powers are limited to suspending falling books in motions? Probably, but they’ll also probably be high since they thought you had magical powers in the first place and thus their minds will be blown. The Invisible Bookend is made of mirrored stainless steel and holsters more than three feet of books. Perfect for anyone with a keen eye for minimalist design (this is about as minimal as it gets) and a penchant for messing with people’s heads.
