Bent Tin Can (Fallout 3)

The 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.

Note
Bent tin cans CANNOT be used as a component for the Nuka grenade.
