I have always wondered how a plasma ball works. Why do those filaments of blue light follow your hand and fingers whenever you touch the ball? Why is there no burning feeling at all? The answers are all here, and they sound too technical to understand. Still, I think what attracts many people to this ball is the mesmerizing play of the snakes of blue light.

Il hypnotise ! Une regard et curiosité ordonneront au-dessus de toi. C'est une boule de plasma. Elle a été inventée par Nikola Tesla et plus tard improvisée par Bill Parker. J'ai pris cette photo à l'intérieur du musée de CERN à Genève.
