Does this video have a physics behind or it is fake? Where the energy comes from? It looks like a perpetual motion!

    $\begingroup$ Aren't a few minutes of observation a pretty small fraction of eternity to make such an extrapolation to perpetual motion? $\endgroup$

    $\begingroup$ LOL, I could have determined it was a Czech accent after 3 seconds of the audio. And I was right. ... There are many ways how to create this video. For example, there may be some alternating magnetic field beneath the table. The YouTube user has posted lots of optical illusions and other tricks so this is just another trick, I guess. $\endgroup$ Apr 10, 2013 at 10:08

It doesn't appear to be fraud (as suggested on Skeptics), but rather a good joke. The YouTube video ultimately links to this disclaimer for a great little website.

Apologies if I ruined the joke.

    $\begingroup$ @Richard The video and the website are jokes. But good jokes. (And one can only guess how he does it.) I especially like the things he does with (the button on) his power extension cord. $\endgroup$
