tour finally begins, and Wonka describes a dizzying array of fabulous chambers and exotic rooms, each devoted to the creation of various sweets and treats ("In This Room Here"). Wonka leads the tour group through a chamber in which the walls and ceiling appear to be closing in around them, and they appear in the Chocolate Room. Wonka introduces his workers, the Oompa-Loompas. Augustus sneezes into the chocolate river and is sucked into a large pipe. Wonka, with little apparent concern, directs the Oompa-Loompas to take Mrs. Gloop to the Strawberry-Dipping Room and retrieve Augustus. The Oompa-Loompas share a moral message about the dangers of gluttony ("Oompa-Loompa One"). Wonka and the remaining guests board a pink candy boat. Veruca Salt demands that her father buy her both the boat and one of the Oompa-Loompas. Salt attempts to buy them from Wonka, but Wonka is unimpressed. The boat ride then turns into a psychedelic nightmare as Wonka navigates them through what appears to be a tour of the darker aspects of human imagination, complete with frightening projected images ("There's No Knowing"). Wonka laughs maniacally and the others scream with horror until the boat abruptly vanishes and the party finds themselves in Wonka's Inventing Room. In the Inventing Room, Wonka reveals one of his creations. A three-course meal in a piece of gum. Heedless of Wonka's half-hearted warnings that the gum is not yet perfected, Violet is unable to resist it ("Chew It") and blows up into a blueberry and is taken to the Juicing Room to be squeezed before she explodes. The Oompa-Loompas share a warning about the evils of excessive gum-chewing ("Oompa-Loompa Two"). Wonka and the remaining guests proceed to the Fizzy Lifting Drink Room, which is filled with bubbles. Wonka informs everyone that the drink will cause the imbiber to float, but forbids anyone to partake. Charlie and Grandpa Joe linger behind after the others leave, and the Oompa-Loompas tempt them to sample the drink. They do so, and immediately rise into the air ("Flying"). They soon find that they're in danger of being sucked into a giant fan on the roof of the room. However, they discover that burping reverses the effects of the drink, and, via a series of belches, they are able to descend back to the ground ("Burping Song"). Charlie and Grandpa Joe rejoin the others in the Nut Room, where a team of squirrels
