Scream Canisters

Scream Canisters are objects in the films, Monsters, Inc. and Monsters University. Their main purpose is to store up the screams of human kids that the Scarers collect. Then, each Scream Canister would be taken to a different room in the factory, where the screams would be extracted from each canister, and refined into energy. Later, when the company additionally began collecting children's laughs, bigger Scream Canisters were used, and there were Laugh Canisters created.
