- Had one of these in the physics lab store room in college. If you rigged a piece of aluminium sheet (3x5")to swing from a hole in the corner it would swing back and fourth. If then tried to make it swing through the gap between these horns it would pretty much stop cold. Nothing like seeing a piece of moving metal suddenly stop with nothing touching it.

- I remember playing with one of these at school in 1963 (Aged 10) The teacher (Mr Allen) who was something of an expert in electronics said that it was from a magnetron. It was amazingly powerful!
