They also learnt about the water cycle, where water comes from and how our water and wastewater is cleaned.
Anna Killen, NI Water's Outreach and Learning Officer, said: "One of the experiments on how to clean water was led by NI Water scientist, Roisin McDade. The audience got a chance to roll up their sleeves and learn how drinking water is cleaned. Families also got a chance to see sewage sludge up close through a microscope, and see the types of bacteria that live in our wastewater."
NI Water's Education team supported the final closing day of the Science Festival with a stand at the Whitla Hall, Queens University.
