Experiment with your perception of distance and size by making the amazing Ames room illusion in this fun experiment for children.

We know that a toy car is much smaller than a real one, but when you hold a car up to your eye and compare it to a car in the distance, they can look the same size.
We intuitively understand this, but thinking about why this happens is the start of a fun experiment to investigate how our brains make sense of the three dimensional world around us. In this video, Dwain and Sahara learn a simple trick to make their drawings look three-dimensional, and then build an Ames room: a classic illusion that plays a trick on your mind with strange proportions.
