This video shows a cool trick involving a powerful electromagnet and balls with controlled electromagnets inside them. The result looks very cool. According to the video, the balls are controlled by a computer, which is what allows for the intricate patterns.
From a physics standpoint this video looks fake, though. It wouldn't be easy to control them as shown (they would likely all be attracted to the magnet due to the inverse square law), and a number of things are wrong - for example, no shadow is cast by the ball statue. It would be far easier to produce this through a video editing program.
But is it fake, or not?
As I speak it is going viral. I checked five minutes ago and it has gained about 2,000 views.
