A cool Christmas

There might have been no snow, but the Royal Society of Chemistry Christmas Lecture was a chilly experience! 400 pupils from schools across West Yorkshire gathered at the University in December to watch Paul Jarrett of BOC gases present a cool introduction to a selection of well known gases. Paul used nitrogen, carbon dioxide and helium at both room and cryogenic temperatures to wow the audience with a selection of weird and wonderful demonstrations including shrinking balloons and home-made fire extinguishers. Willing volunteers helped Paul sample lemonade that he made using just water and carbon dioxide, but the consensus was to stick with the traditional brands!
