Nuka-Cola Clear formula

The Nuka-Cola Clear Formula is a quest item for unmarked quest Just for the Taste of It in Fallout 3.

Background
The formula describes how to make Nuka-Cola Clear, a type of Nuka-Cola invented shortly before the Great War but never mass-produced.

Related quests
Sought by a gang called Sudden-Death Overtime so they might profit from it and bring back ice hockey, the formula is located in the R&amp;D section of the Nuka-Cola Plant, with the gang located near the Red Racer Factory.

You can give the gang the recipe for 250 caps or pass a speech challenge to raise it to 400. Killing Goalie Ledoux, the leader of the gang, doesn't result in any negative Karma, contrary to pickpocketing him in order to reclaim the recipe. Please note that you can do nothing with this formula, so if you choose to kill Goalie Ledoux without selling the recipe, you will gain nothing. If you drop the formula before giving it to Goalie Ledoux and then talk to him, he will still accept it and then you can get two (see video).

Behind the scenes
This is most likely a reference to Crystal Pepsi or Tab Clear which was released but was never popular.
