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.

Maddie is preparing for bath time. She uses a special thermal imaging camera to find out how the hot water system in a house works and then visits a reservoir to see where the water comes from and how it is sent to our homes. Next, Maddie visits a toothpaste factory to see how toothpaste is made from different ingredients and uses a special slow motion camera to find out how the stripes get inside a tube of stripy toothpaste.
