Tin Can (Fallout: New Vegas)

Tin cans are miscellaneous items

Gameplay
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.

Uses

 * Tin cans are one of the components in crafting powder charges.
 * With Gun Runners' Arsenal, they are used to craft Nuka-Grenades and tin grenades.
 * In the Dead Money add-on, they are used as a component for the Sierra Madre martini.
 * Also in Dead Money, with the Junk Rounds perk, tin cans can be used along with scrap metal, and various cases and hulls to make "junk rounds." This requires five tin cans, one piece of scrap metal, and a case or hull for the ammunition desired.
 * 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.
