Hand-cranked pencil sharpeners work just fine, and maybe that is what makes them a perfect object to get the heavy duty treatment. And if a nitro pencil sharpener wasn't enough for you, YouTuber Giaco Whatever upped the ante to a 1000cc, two-stroke engine.
"This thing is a beast," Giaco in a behind the scenes video. Initially from a jet ski, the engine didn't come with a cooling system—the builders had assumed that any cooling the engine would need would come from surrounding water. To keep things from overheating, Giaco installed an external cooling system to feed the engine water. What it lacks in practicality, it makes up for in being absolutely ludicrous.
