The Dwarf and the Giant Optical Illusion is a very cool illusion, at first it seems quite puzleing, how the heck could he be so big and the other guy be so small? No theres no midgets or giants here, if you look at the second picture you will see they have switched sizes. This Illusion is made using an Ames Room.  Ames rooms work by giving you a false perspective, the room is made in such a way that it it appears normal yet one side is very close and the other side is a fair distance back :)

The Dwarf grew up bigger then the giant!
