Thermal conductivity
Another example of silver's thermal conductivity is to put different materials on ice cubes.  An iron washer will just sit on the ice and slowly become colder.  A copper penny will melt through the ice cube and become colder faster.  A silver coin, spoon, or ring on the ice cube will sink into it almost as though the ice cube were made of thick syrup, and the silver will become ice cold almost instantly.  Again, this is because the silver is really good at drawing heat from the air and giving it to the ice cube.  Copper is also good at this, but not as much as silver.
