In this activity about depth perception, learners create an optical illusion in a shoe box. By looking through the viewing hole, learners explore how they can trick their brain into thinking that two similar objects of different sizes are really the same size. The trick is in the special construction of the box, and because their depth perception is impaired when they close one eye.
