Alien's Device Prop

Origin
During the filming of the twenty second episode of the first season of The Twilight Zone Rod Serling was watching as the director cued the power to go out. There had been a master switch to shut off the power of the set however sitting nearby was the alien prop box and when the switch was flicked the box was also zapped. The next day however the power was only active for a few hours during the day. Looking into it Serling discovered that one of the actors playing the aliens was switching the switch on the device back and forth without realizing it. After filming was finished Serling took the device from the rest of the props and had it delivered to the Warehouse.
