Maddie is getting ready for a party. She uses a special camera and animation to find out how cake ingredients work together to make cake sponges rise in the oven. Next, Maddie visits a factory to see how a soft play centre is made. She uses a special microscope camera to look at the foam stuffing and sees how all the pieces are sewn together to make play shapes. Finally, she sees how an airbrush is used to make the wings of a rocking parrot.
