Using an empty fizzy drink can and a bowl of water, heat a small amount of water in the can over a Bunsen burner. Then flip over into a bowl of cold water and the change in temperature will cause such a change in pressure that the can will be ‘crushed’. It is worth practicing this one a few times!
Great as a class demo to introduce changing states of matter.
