Bent Tin Can (Fallout 3)

Bent Tin Can is an item in Fallout 3, useful only as Rock-It Launcher ammunition. They can be found almost everywhere (you're likely to run over them at every occasional moment), so if you've grown a liking to your Rock-It Launcher, you don't really need to worry about ammo.

Interactions with the Player Character
After completing the Blood Ties quest, Brailee Ewers rewards you by baking you "cookies", as she calls them (which are nothing more than Bent Tin Cans).
