Simple Paper Trick Demonstrates Visual Illusion
This video demonstrates a simple visual illusion using a small square of paper and a marker. An individual draws arrows on the paper to show how rotating the object can change the perceived direction of the arrow, creating a basic optical effect. The clip features a young child observing the demonstration, followed by a close-up tutorial showing how to replicate the trick by drawing arrows on a square piece of paper and rotating it to change the orientation. The content is presented as a quick, easy-to-follow activity.
