Remember those optical illusion books where you focus on the image of the old crone until it looks like a beautiful young woman? These books are a mainstay within elementary school science classes to illustrate the tricks our mind can play on us.

From beds that look like they're floating in midair to commercials that present one optical illusion after another in rapid-fire fashion, these unique products prove that our fascination with the disconnect between mind and vision continues even beyond childhood.
