How can you decrease the thermal energy off a can of soup just taken out of your pantry?

If you just want to decrease temperature of the can, you could:

• run cold water over the can
• put the can in a bowl of icecubes
• put the can outside during cold temps, or plop it into snow

You could also dump the soup into a container, leaving just the can which would cool the metal faster than if the soup remained inside the can. Then you could cool both the inside and outside of the metal at the same time, rapidly decreasing the temp.
