The Juicing Room is a room in the Wonka Chocolate Factory, specifically for juicing fruit.
Purpose
The purpose of the Juicing Room is to juice things.
The Juicing Room came in handy when Violet Beauregarde chewed on Willy Wonka's experimental three course meal gum, and the effects of the dessert which was blueberry pie, turned her into a giant blueberry. The juice kept filling inside her causing her whole body to stain blue and expand into a giant round human blueberry. In order to save Violet the Oompa Loompas rolled her away to the Juicing Room. The 1971 film put more emphasis on the effects of the gum: if Violet wasn't juiced, she would eventually explode. In the 1971 film it is not known what happened to her but at the tours end Mr. Wonka assures Charlie that all the other kids will be "quite alright." and "completely restored to their normal, rotten selves.".
Trivia
The juicing room is were Violet, as a giant blueberry, is rolled away to in order to squeeze the juice out of her body before she explodes.
