The obedient cylinder (Illusion)

 I've found another interesting illusion here I present a Spinning cylinder which can spin clockwise or counter clockwise simply by blinking.

To do this trick all you have to do is blink once while watching the spin of the cylinder and expect it to alter its spin. Flicking your eyes in the direction you want it to spin also works.

Go ahead and try it yourself:

What is interesting about this illusion is that the motion of this cylinder is indeed imaginary because in fact the particles are emitting randomly at each other from two roughly straight lines and everything including the cylindrical shape exists only in our imagination.
