Illustration of Catalyst Science Centre

A hands-on science centre in a former chemical works, topped by a glass observatory with views up and down the Mersey. Small enough to do properly in two hours, cheap enough to repeat.

It is the thinking-family's wet-morning option: interactive galleries below, the rooftop as the finale, and Victoria Park's splash pad five minutes away if the sun appears.
