A fictitious device used to move heavy objects in space, even though they are not subjected to gravity and thuis have no weight. This makes the device completely useless and absolutely ridiculous.
Guy 1: Hey, wouldn't a space crane be a great idea?! You could move heavy stuff in space!
Guy 2: ... No. That makes absolutely no sense. Shut up, Ron.
