In Monsters, Inc., what is the name of the machine designed to extract screams from children?

In Monsters, Inc., the machine designed to extract screams from children is the Scream Extractor.

The device is part of Randall’s plan to solve the energy shortage facing Monstropolis. Rather than relying on ordinary door-based scaring, the machine is intended to forcefully obtain screams from a child and collect them at a much higher rate.

The Scream Extractor is hidden in a secret testing area and is used on Boo after Randall captures her. Sulley discovers the operation and understands that the machine would seriously endanger her. The sequence turns the factory’s familiar energy system into a direct threat.

The machine also marks the moral failure of Waternoose and Randall’s scheme. After the plan is exposed, Monsters, Incorporated abandons the approach. The film instead embraces laughter, showing that a safer and happier interaction with children can produce more energy.
