Do you believe that these balls are moving in a straight line?  This will blow your mind.

Illusionist Bruss Pup has done it once again! The balls that you see bouncing around in this red circle appear to be moving as one single unit.  Right?

A circle of white balls rolling around the larger red circle.

But the reality is, the white balls are just moving in straight lines. Can you see it? Watch as each ball is added one at a time.

That is all.
