Bottlecap Mine (Fallout 3)

A Bottlecap Mine is a landmine that can be made, with the proper Schematics, out of a Vault-Tec Lunchbox and Bottle Caps.

The Schematics are a quest reward from Moira in Megaton after the Minefield quest, but can also be obtained from a traveling merchant. A schematic other than the one acquired from Moira as a reward can be found in a Nuka-Cola soda shop East of Girdershade. The Schematics can also be found at Jacko's Pop & Gas Stop. Northwest of Tenpenny Towers. You can also get the Schematics from Dashwood's safe, in Tenpenny Tower. You can also get the Schematics from the child vendor in Little Lamplight.

Multiple Schematics will increase the effectiveness of the Bottlecap Mine design and productivity. For example: after finding a second schematic, the items required to make only one mine, now creates two. Two for the price of one.

Additionally you can steal the bottlecap mines from any weapons workshops(workshops are in any weapons shop). They can also be found in various other places on top of Workbenches.
