More than 300 people poured through the doors of the London Place attraction for half-term science fun on Wednesday last week.

Among the shows was Super Cool Science by schools programme manager Natalie Ford, pictured.

She said: β€œIt was mostly about the science of very cold things. The children were very enthusiastic.”
