Does Salt keep ice from melting?

Which Cooler keeps ice the longest?

What happens when you put ice with salt?
When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.
