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 after the Minefield quest but can also be obtained from merchants. 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. A schematic other than the one acquired from Moira as a reward can be found in a Nuka-Cola soda shop East of Girdershade.

Items Required: Lunchbox, Cherry Bomb, Sensor Module & 10 Bottle Caps

Or you can steal the bottlecap mines from any weapons workshops.(workshops are in any weapons shop.)

Schematics can be found at Jacko's Pop & Gas Stop. NW of Tenpenny Towers.
