Exibido em:: Set 13, 2016

Maddie is out and about exploring different ways to travel. She uses a special underwater camera to see a boat propeller in action and an animation reveals how the propeller pushes the boat through the water. Next, Maddie visits a factory to see how a hot air balloon is made from lots of pieces of material sewn together. She then joins a balloon team outside to take a ride in a finished hot air balloon.
