Anyone who has ever stepped foot in a child's bedroom can tell you that Lego bricks make for some very effective calthrops. Joerg Sprave, the Internet's go-to slingshot expert, has taken that weaponization one step further with a slingshot custom built to shoot the tiny bricks.
While Lego does accept suggestions for new sets (often with very cool results) it's unlikely that they would fund mass production of Sprave's Lego-shooting pistol, even with its terrific accuracy. Perhaps he'll just stick to spinning knives.
