In this adaptation of Roald Dahl's 1964 children's novel, “Charlie and the Chocolate Factory,” poor Charlie Bucket (Peter Ostrum) finds one of five Golden Tickets hidden among candy maker Willy Wonka’s famous Wonka Bars and receives the opportunity of a lifetime: a tour of the mysterious Wonka's Chocolate Factory. Charlie’s Grandpa Joe (Jack Albertson) accompanies him on the tour. About halfway through, as other kids in the tour group are eliminated for failing to show character under the duress of fountains of chocolate, Charlie and Grandpa Joe sneak a drink of a strange soda and are drawn into a ventilation shaft full of bubbles, up toward a menacing propeller fan. The solution? Burping, of course. As the two belch, they are gently let down, and disaster is avoided. Warning to engineers: Charlie and Grandpa Joe are trained professionals. Do not try this at your desk.
