Atomic Cocktail

 is a consumable item in Fallout: New Vegas.

Characteristics
When consumed the player is resistant to fire and energy and SLP is greatly reduced, while H2O is increased, but it also gives +8 to radiation.

This item is made at any campfire. It requires: Mentats (1), Nuka-Cola Victory (1), and vodka (1), which makes 4 bottles of the cocktail. It is not recommended you make it yourself without the Nuka Chemist perk, as Nuka-Cola Victories are normally very rare. Atomic Cocktails however can be bought at many vendors and found in many refrigerators.

Prior to patch 1.2.0.31x, atomic cocktails required an additional 1 Nuka-Cola Victory, 1 vodka, and a bottle of wine to craft.

Behind the Scenes
It is likely a reference to the song Atomic Cocktail (1946) by the Slim Gaillard Quartette.

Also, the Atomic Cocktail was an alcoholic drink served (among other places on the strip) during nuclear weapons testing in the 1950's in Las Vegas' Sky Room, where tourists could view mushroom clouds form at the Nevada proving grounds from a distance. This was a considerable tourist draw from 1951-1963 when Las Vegas was also known as "Atomic City". Las Vegas businessmen had, at the time, a penchant for marketing everything as "Atomic".
