Empty soda bottle (Fallout 3)

The empty soda bottle is a miscellaneous item in Fallout 3 and Fallout: New Vegas.

Fallout 3
The empty soda bottle only serves as a common form of Rock-It Launcher ammunition.

Fallout: New Vegas
You can squeeze the water out of two prickly pear fruits into an empty soda bottle to form a bottle of purified water which essentially is cactus water. In the Honest Hearts add-on, it is the required component for brewing Homebrewed Nuka-Cola. In Old World Blues, the Sink can turn this into a bottle of purified water.
