Scientists discover just how runny a liquid can be

Scientists from Queen Mary University of London and the Russian Academy of Sciences have found a limit to how runny a liquid can be.

Viscosity, the measure of how runny a fluid is, is a property that we experience daily when we fill a kettle, take a shower, pour cooking oil or move through air.

We know that liquids get thicker when cooled and runnier when heated, but how runny can a liquid ever get if we keep heating it?
