Series 4: 15. Climbing Wall and Modelling Clay
Today, Maddie is learning about colourful things! She visits a climbing wall centre, where she finds out how colourful holds on the wall help us to climb up it. And we learn how an auto-belay is used to help us to go up and down the wall safely.\n\nNext, Maddie heads to a modelling clay factory to see how brightly coloured modelling clay contains a plant ingredient called starch to make it thick. Maddie uses her special time-lapse camera to let us see all the ingredients mixed together by a big machine that turns the big lumps of clay into smooth modelling clay. We discover how an airtight tub helps keep the modelling clay malleable so it can be played with again and again.
