Ames Illusion Room

An Ames Illusion Room is a distorted room that creates an optical illusion. You’ve probably seen it in movies like The Hobbit, Harry Potter or Willy Wonka and the Chocolate Factory.

When viewed, it appears to be an ordinary cubic-shaped room. However, this is a trick of perspective. The true shape of the room is trapezoidal, meaning the walls are slanted and the ceiling and floor are at an incline.

As a result of the optical illusion, a person standing in one corner appears to be a giant, while a person standing in the other corner appears to be tiny. The illusion is so convincing that a person walking back and forth from the left corner to the right corner appears to grow or shrink.

Learn how to make one for yourself in the excerpt below.
