Homemade Grappling Gun
An engineer who goes by “JT” online has been fascinated by the grappling hooks used by Batman and other superheroes in movies. So, he went on to build his very own, and it wasn’t easy, since the entire process took over a year. What he ended up with was a aluminum chassis that packs a powerful 10,000W skateboard motor, attached to a custom-built grappling hook. The hook itself is propelled using 12g CO2 cartridges, operated by an an analogue throttle wheel controlled with your thumb. Read more for a video and additional information.

Since the throttle wheel is thumb-operated, the gun can both pull someone upwards and let them drop downwards after. For now, it’s capable of shooting 45-feet of cord wound up in the machine to the top of a climbing wall and elevate the wearer 33-feet in just 3-seconds. A few caveats: it’s hard to control and puts quite the strain on the wearer’s arm. What’s next for this engineer? How about a Spider-Man web shooter that will also be fully functional, or so we hope.
