Youngsters descended on the University of East Anglia for a day of bright sparks and colourful flames.
Around 160 Year 7 and 8 students swapped school uniform for goggles and lab-coats yesterday as they took part in the nationwide Salters' Festival of Chemistry.
The two-day event, held at the School of Chemistry, involved hands-on challenges and laboratory experiments, and gave pupils a glimpse of university life.
They saw the award-winning Kitchen Chemistry spectacular science show, delivered by lecturer Dr Stephen Ashworth, who demonstrated what people can do in their own kitchens, including colour-change experiments and food-based tests.
Small teams of pupils also took part in a murder-mystery game, using CSI-like chemical tests to discover which of their teachers was the killer.
City of Norwich School, Sprowston Community High School, and North Walsham High School took part in the activities, with Pakefield Middle School winning Wednesday's University Challenge award. The UEA has been a part of the Festival of Chemistry since 2001.
