THE secrets behind fingerprint techniques, laundry detergent and chip-pan fires were revealed to teenagers yesterday in a chemistry event designed to boost interest in the science.

The two-day workshop, Chemistry at Work, held at Durham University's biological sciences building yesterday and today, was set up to inspire pupils to take an interest in chemistry.

Pharmacists, forensic scientists and employees from several pharmaceutical companies showed more than 300 students from schools across County Durham a range of experiments designed to improve their understanding of science.

Organiser Gail Tolfree, from Setpoint County Durham, which is part of the County Durham Business and Learning Partnership, said: "This is an excellent way to show pupils how the science they are learning at schools is used in local companies."

She added: "It demonstrates the wide range of scientific jobs available."
