The Olympics are supposed to be a series of competitions that test the physical capabilities of the competing athletes. But increasingly, it seems like it’s become a competition over which athlete brings the best gear: be it highly-engineered running shoes, swimsuits, or sleds. So why shouldn’t track and field…

Joerg Sprave has finally built an elastic-powered weapon that even the burly slingshot master can barely handle when the trigger’s pulled. It’s a handheld trebuchet (a type of catapult) that flings circular saw blades for hundreds of feet, and it looks almost as terrifying to yield as it is to be in the weapon’s…

Star Wars cosplayers of the world take note: Joerg Sprave, the internet’s favorite slingshot-designing mad scientist, has come up with a clever way to simulate blaster fire in real life. Instead of employing dangerously powerful lasers that will get you kicked out of a convention faster than you can reload, his…

Amateur life-risker Joerg Sprave has successfully built custom slingshots capable of firing everything from bowling balls, to Christmas trees, to lethal Lego bricks. His latest creation, a slingshot that can launch full-size swords, is as ludicrous-sounding as it is awesome to see in action.

Joerg Sprave, the internet’s most famous slingshot-loving amateur super villain, has found ways to weaponize everything from foam Nerf darts, to those tiny Ikea pencils. His latest troubling achievement is a custom elastic-powered blaster that can turn Lego bricks into tiny projectiles.

Even the most mild-mannered among us can’t spend an afternoon inside a sprawling IKEA warehouse without leaving full of rage. But if you want to drown your frustrations, do it in cheap hot dogs and soft serve ice cream instead of walking out the door, determined to weaponize those tiny IKEA pencils.

To celebrate reaching a million subscribers on YouTube, the internet’s favorite slingshot-building madman, Joerg Sprave, has engineered his largest creation to date: a massive elastic-powered weapon that turns bowling balls into flying projectiles.

Last week, slingshot mad scientist Joerg Sprave showed the world how to weaponize a Nerf blaster using scalpel blades. But since that apparently wasn’t dangerous or terrifying enough, this week Joerg’s back with a follow-up tutorial that explains how to make the whole thing fully automatic.

As much as we’d love for slingshot-designer Joerg Sprave to visit the US on a publicity tour, it’s creations like this—a Nerf blaster made lethal using razor-sharp scalpel blades—that will probably result in him being barred entry to the country.

Joerg Sprave, the internet’s favorite weaponizer of perfectly safe and innocuous objects, is back with a build that will up the risk factor at your next picnic. Because while getting hit in the head with a Frisbee might hurt, getting hit in the head with a Frisbee covered in surgical scalpels is a guaranteed hospital…

Strict safety regulations and litigious lawyers mean your kids’ toy foam blasters don’t have a lot of power behind them. And that’s a good thing, unless you spend you days making insane slingshot creations and have decided that Nerf’s Rebelle Bow Blaster needed an upgrade like Joerg Sprave did.

It’s more surprising that lawn darts weren’t banned until 1988 in the US, instead of the day after they first went on sale. And if you need a good reminder as to why you can no longer easily buy a set, Joerg Sprave built a lawn dart slingshot cannon that explains why.

His true passion might be designing and building some of the most ridiculous slingshots the internet has ever seen, but even Joerg Sprave needs to stretch his creative wings from time to time. Which is why Joerg's most recent creation is an insane chainsaw-powered wooden machine gun that can decimate a target firing…
