The time a substance stays cold is function of:

- It's ability to store heat (heat capacity)
- The rate at which it gains / loses heat (radiosity, conductivity).

So, since water has an unusually high heat capacity and a relatively low conductivity, it stays cold for a longer time than most frozen liquids would.

One with a poor conductivity and high specific heat.

Water works pretty well.
