File this one securely in the mischief category. This is the xProducts Can Cannon ($399). This 12-ounce can launcher uses a standard AR15 body to launch the cans about 100 yards using .223 blank rounds.
The launching barrel of the Can Cannon can shoot other similarly sized objects like oranges, tennis balls, etc… The company is working on developing additional projectiles like grappling hooks and net launchers. Two thumbs up!
