Novelty inventions such as hot knife for spreading hard butter and a magnetic key.
Part of THE VERY IDEA issue.
Pathe Studios, London.
Various shots of people trying out novelty inventions:
A pencil holder - the pens stay put even when it is turned upside down. A man places it in his jacket pocket. A golf practice device - the club hits the ball which is on the end of bendy rubber stick. A safe controlled by a magnet key. A combined fork and spoon. A hollow knife - it can be filled with hot water, making spreading hard butter much easier.
Various shots of a "mad professor" (looks like an actor in costume). He demonstrates a laser device that pops a balloon.
