Each year, pupils from all over the East of England compete to grow the best crystal of potash alum possible, in the Eastern Region Crystal Growing Competition. This year, during the International Year of Crystallography, the competition was hugely popular, with nearly 80 schools participating in two age groups.
The top prize in Key Stage II went to Laxton Junior School near Peterborough, with Robert Arkenstall Primary School, Haddenham in second place.
