An Inventor Has Made His Own, Personal Grappling Gun

An Inventor Has Made His Own, Personal Grappling Gun

“I could travel up a building at about a storey per second.”

I don't know about you, but I've always been envious of the superheroes and video game characters who have a grappling hook up their sleeves, sometimes literally. It gives you a getaway that is not only quick but super stylish too. Oh, excuse me, is that the time? I must be off. Goodbye, Mr Wayne. (I tried to type an onomatopoeia for the sound of a grappling hook shooting off into the sky, but nothing really came close.) Now, this inventor actually built his own grappling gun, it works like a charm, and we're Joker-green with envy here at GAMINGbible.

This is pretty par for the course for JT, who runs the YouTube channel BuiltIRL. He's made Spider-Man's web shooters and given himself the power of Force lightning when holding a replica of Rey's staff from Star Wars: Episode IX - The Rise of Skywalker. While some started new hobbies like crochet, and others challenged themselves to get fitter and stronger, JT spent almost all of last year spending his free time creating a fully-functioning grappling gun, and crucially, one that is able to fit on his forearm like the ones from Titanfall 2, Assassin's Creed Syndicate, Just Cause, and more.


Beginning with an older prototype, he got to work and developed the final product. The gun works by using a carbon dioxide-powered blasting mechanism with standard cartridges: that's what propels the hook out of the gauntlet and upwards onto the surface of whatever is nearby. It also uses a 10,000W motor to rapidly pull his body towards the hook, and impressively, the surrounding chassis is strong enough to withstand the power and pressure.

If you're wondering how the man doesn't dislocate his shoulder every time he deploys it, he's made adjustments to account for the comparative frailty of the human body compared to video game characters. He wears a harness, which dissipates the force of the pull across a wider surface area, so that JT isn't hauled upwards by his arm alone.

JT took the grappling gun to his local trampoline park to test it, and the results are stunning. "I got 10 metres up the wall in just over three seconds," he said. "That means I could travel up a building at about a storey per second." What's more, the inventor's grappling gun is able to let him fall from the hook slowly, thanks to a wheel that controls his direction and speed of ascent and descent. Though it's a bit unwieldy on occasion, it's an exceptional piece of DIY tech, so hats off to you, JT. And this is your sign to (re)play Assassin's Creed Syndicate, because zooming across Victorian London is very fun, actually.
