Bawls Bottle

Bawls Guarana (named Bawls Bottle in-game) is a consumable item in Fallout: Brotherhood of Steel.

Background
Bawls Guarana started as the brainchild of a then 20 year-old college graduate named Hoby Buppert, who was looking for an alternative to coffee in 1997. As part of a class project, he came up with a carbonated and non-alcoholic beverage made with guarana, a highly caffeinated berry native to the Amazonian rainforest. Named for the caffeinated "bounce" it gives you, which contains a natural form of caffeine nearly three times stronger than that found in traditional sodas.

Looking for a place to settle, Hoby Buppert chooses Texas, a quiet place, conducive to the growth of Guarana. The company markets its drinks only in Texas forever, never looking to emigrate because of the market leader, the Nuka-Cola Corporation. But before the Great War, Bawls Guarana concluded a lucrative contract with Vault-Tec, which wanted to build the Secret Vault in Texas. They sponsored the construction and only its product was allowed in the vault, at the expense of Nuka-Cola, non-existent in this region.

Characteristics
Despite advertising in Carbon, you can find Bawls bottles only in the Secret Vault, especially in the Bawls vending machine that contains 9 bottles (and 4 more if you destroy the machine). Each bottle will heal you 1/4 of your Hit Points until 2/5 with the skill First Aid at maximum level.

Behind the scenes
The drink is sold at a variety of collectors' sites such as Thinkgeek.
