The Dark Knight uses some pretty cool technology. A fan favorite is a gun that shoots a grappling hook, with a line attached. Once secured, the line pulls Batman straight up into the sky. BYU engineering students took inspiration from Batman to create an anchoring device that shoots from a firearm and pulls a person vertically in the air as much as 90 feet, just like the Caped Crusader is known to do from time to time.
