Perception and Optical Illusions

The video explores an optical illusion using cupcakes to demonstrate how our brain perceives size based on surrounding objects. Participants are asked to judge the size of two identical cupcakes, leading to a discussion on perception. The Ebbinghaus illusion is explained, showing that our brain interprets size relative to nearby objects. The video concludes with plans to further test the illusion with more volunteers.
