Mercury will be our answer.

As we know, our lovely thermometers contain mercury (mostly old fashioned kinds now), and the only way that we could see the temperature through a thermometer was by seeing the liquid inside of the thermometer rise and fall. If mercury were to be a solid, then it wouldn't be able to rise or fall.
