A Manual Projectile Dropper (Made From a Cereal Box)

Yesterday, I thought of making a box that would drop things by pulling a string. An hour later, I made this, and around 50 aluminum balls and some paper balls as the ammo. I think this will also drop things like K'nex pieces and Nerf darts. I'm post the instructions when I can think of a name for it...

It's a very simple, but effective trap for using in "wars"! :]

Help me by thinking of some names for it! :D
