Capacitors- Van De Graff Generator

Hi, i created this video with sparking Animation to explain a Van de Graff Generator within 1 and 1/2 minutes flat. This was indeed a difficult challenge. It's a tough subject for anyone to imagine and understand this great mechanism. On one side of the belt, we have the Positive charges going up, on the other side of the same belt, how do Negative charges come down ? Well, see the video. I hope I have done some justice to this topic to make it easier for young students to get a quick heads-up . A remarkable invention by the scientist Mr. Van De Graff.
