Magic window

The Magic Window STEM kit introduces children to the captivating world of optical illusions and rotational motion. Through constructing this kit, they will learn how the inverse rotation of two wheels with specially designed patterns can create mesmerising visual effects. This phenomenon is a practical demonstration of the Moiré effect, where overlaying patterns with slight differences in alignment or frequency can produce the illusion of motion or depth when they move relative to each other.

Furthermore, the kit allows children to explore the principles of rotational symmetry and periodicity. They will see how the speed at which the wheels turn and the angles at which the patterns are observed affect the visual outcome, providing an understanding of how variables in rotational systems can dramatically alter the perception of the observer. The Magic Window kit is not only an enjoyable way to engage with physics but also an opportunity for kids to appreciate the beauty and complexity of visual perception and the interplay between motion and design.
