Some water in a tin with lid which can be tightly screwed on its open mouth. The water is heated to boil and the steam from boiling water is allowed to escape for sometime. The open mouth is sealed with air-tight cap and the can is cooled under tap-water. The sides of the can are crushed and get deformed.

Solution

Escaping steam carries the air from the tin can and on being cooled the water vapour (steam) inside the can condenses and creates a vacuum. The tin's pressure inside the can is then greatly reduced. The air pressure outside the can presses it and the outside pressure being high, the can is crushed and deformed.
