Making Microwaves visible with a little Help of a Neon Bulb Matrix

Zeke Kossover hat eine Plexiglasscheibe mit einer Matrix aus winzigen Neonröhren bestückt und diese in eine Mikrowelle gestellt um die Wellen darin sichtbar zu machen. Interessant!

Microwaves are invisible, so you can’t see them inside microwave oven, but their presence can be detected with neon lamps. The changing electromagnetic field from the microwaves will make charged particles move, and so the electrons in the metal legs will move creating current. This current makes the lamps glow.
