MMX Marshmallow Crossbow / $125
Forget Nerf guns — the best holiday house battles are staged with ammo you can eat. The Marshmallow Crossbow is designed to sling the sugar-based pellets up to 60 feet through the air. It's handmade from 99% natural materials and coated in an Uncrate-exclusive blackout coating, and works best with slightly dry marshmallows. Pro tip: Add a bit of cornstarch to fresher 'mallows to improve their flight and mark your target.
