A nice little magic trick, acted out in what I think is a funny way... Anyhow: there's no video trick in there that would manipulate the lamps. I only enhanced them because the spotlights of the stage made them almost invisible.
Note that I will not approve comments that "reveal" the trick in order to maintain the fun for others...
