The power capabilities of a hydraulic press are dependent on a few variables, such as cylinder size and level of pressure applied, but suffice it to say that most presses are quite strong. Typically, the machinery is used for forging, clinching, moulding, blanking, and other metal-forming operations. Oh, and defeating the Terminator once and for all.
It should come as no surprise that people who have access to a hydraulic press get curious about what happens when you crush various things with it. One such curiosity centered on a hockey puck, which is a notoriously dense and "indestructible" object. Turns out when you put it under the menacing force of a hydraulic press, that second description loses its potency.
