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.
Joerg even upgrades the batteries powering the Nerf blaster’s spinning fly wheels so they have quite a bit more kick. Should you try this upgrade at home? Probably not. Should you travel to Germany without a helmet, safety visor, and flack vest? Definitely not.
