In today’s episode it’s playtime! Maddie is finding out about wind-up toys and how they move along. We see inside a wind-up truck and Maddie uses her special cameras to show us how the spring inside gets tighter and tighter and stores energy so that when it is released the cogs inside move the wheels. Next, Maddie visits a factory where cricket bats are made from willow trees, because it’s bouncy and strong. First the tree trunk is cut using a chainsaw and we learn how the wood is shaped using lots of different cutting and sanding machines. We see inside a robot that is shaped like a pineapple! Maddie uses her special slow-motion camera to see all the wood shavings flying off as the bat takes shape. Show less
