Why Do Fidget Spinners Appear To Be Spinning Backwards?

Why do wheels appear to spin backwards? What is the stroboscopic effect? Fidget Spinner appears to spin backwards. Why?

This video shows why a fidget spinner appears to spin backwards. Spinning in reverse is called the stroboscopic or wagon wheel effect. It is also called aliasing. This shows why a fast spinning fidget spinner appears to suddenly reverse direction or spin backwards.

Premium Fidget Spinners can often look like they are spinning backwards as they have a high centrifugal spin ratio.
