Optical Spinner Illusion Exhibition by Hands On!

Optical Spinner Illusion

Can you trust your eyes?

In this experience, a large spiral image spins, creating a strong impression of inward motion. When visitors fix their gaze on the spinning wheel, their brains get used to seeing this contracting spin. By the time they look away, the brain circuits that sense inward motion are exhausted. For a few seconds, other circuits take over and make it seem like stationary objects are pulsing outward in the opposite direction. The large scale of the spinning disc creates a dramatic, dizzying display of this fun illusion.
