A 'chemical reaction' with China

A British scientist has become an online star with short videos of experiments

British chemist David Evans has become an overnight celebrity on Chinese social media. His chemistry experiments have attracted over 2 million followers in just a few months.

Evans is a chemistry professor at the Beijing University of Chemical Technology. The 60-year-old always wears a white lab coat, a pair of safety goggles, and smiles often. Some web users say he looks just like the "grandpa of KFC".
