From DAVID WILLACY
During the last few weeks of warm weather I have been indulging myself with
ice-lollies.
Why is it that if you suck hard, the flavourings and colourants are released
into your mouth, but the basic ice structure is barely melted? I assumed (as
a non-chemist) that these substances had been dissolved in the water, so why
do they separate so easily, just by suction to the ice?
