The presenters of this BBC series – including Tracy Brabin, Simon Davies, Sophie Aldred and Steve Johnson – answered questions sent in by the children at home, using a combination of in-studio experiments and on-location visits to explain the answers.
They were assisted by Jo Korna, a green puppet with a feathered hat, voiced by Robin Stevens.
