Walking Distillation

This term refers only to experienced chemists, as it requires a great amount of skill and experience in order to achieve it. This term consists of purifying a liquid by using heat and cooling while walking in the city of Thessaloniki in Greece. This phenomenon is extremely efficient and very popular in the surroundings of Davitel Tobacco Hotel in Thessaloniki.

Sure, Stephen Hawking was a great chemist, but he was never able to achieve a walking distillation, as he was not able to walk in the streets of Thessaloniki.
