Napalm
In the film Fight Club, the screenwriters were originally going to have Tyler Durden (played by Brad Pitt) recite a working recipe for napalm. However, after questions of safety were brought to the attention of the producers, they substituted his lines with a fake recipe claiming it to be equal parts of gasoline and orange juice concentrate. Contrary to popular belief, the original recipes in the Fight Club book were also modified by its publisher. The book's altered recipes claim that, in addition to orange juice, mixing equal parts gasoline and diet cola, or thickening gasoline with cat litter, will work.
