Today, Maddie is having a fun day out. She uses a special thermal camera at an ice rink to find out how runny water freezes to make solid ice we can skate on. Next, Maddie heads to a bouncy castle factory to see how a bouncy castle is made from lots of different coloured pieces of material sewn together. She then has a go at bouncing when the finished jungle-themed bouncy castle is inflated and brought to life.
