What tv show was this shot for? It was done presumably in the 80s but for who? The whole they wanted to believe so they felt it seems iffy if in fact the scientists presented were really scientists and really skeptics. Usually thats the point where these things fall apart. Slight of hand is a definit possibility but some back ground on where this film came from would be helpful in establishing the legitimacy of the documentary itself. The bit with the LED was interesting.
