Tin Can (Fallout 3)

The tin can is a miscellaneous item in Fallout 3 and Fallout: New Vegas.

Characteristics
Tin cans are sealed metal containers used to hold and preserve perishable food, such as Pork n' Beans. Their airtight seal allows food to keep for years, though all tin cans found are open, empty, and unlabeled. In-game, they are typically found either in places where food is or was once sold, such as grocery stores and gas stations, or alongside camping grounds and hideouts.

Fallout 3

 * Used as ammunition for the Rock-It Launcher, tin cans are especially useful due to their relatively low weight, expendability, and prevalence.
 * They are an essential component in the creation of nuka-grenades.
 * You can't make Nuka-grenades with bent tin cans, which is a different item.

Fallout: New Vegas

 * With Gun Runners' Arsenal loaded, they are used to craft powder charges, nuka-grenades and tin grenades.
 * In the Dead Money add-on, it is used as a component for the Sierra Madre martini.
 * Also in Dead Money, after you get the Junk Rounds perk you can use tin cans, scrap metal, and the various cases and hulls you find to make "junk rounds." This requires five tin cans, one piece of scrap metal, and a case or hull for the ammunition you would like to make.
 * Tin cans are among the pieces of junk metal accepted by Isaac in the unmarked quest Dealing with Contreras for fulfilling the McCarran arms request.
