Colin Contraption

In reference to the popular Youtuber Colin Furze, a Colin Contraption is a device that has been haphazardly constructed and with a purpose so outlandish that it should definitely 100% explode from the moment it is activated under any given circumstance but instead, by some intervention of God himself, performs its purpose and to a degree that exceeds any reasonable expectation.

Person 1: "Are those fireworks shooting out of his lawn again?"
Person 2: "Yeah, he's built another Colin Contraption."
