Maddie is finding out about repeating patterns. She visits a butterfly sanctuary to learn how the life cycle of a butterfly works. Maddie uses her special microscope camera to show us the marvellous moment when a tiny caterpillar hatches out of its egg, and we see three Owl butterflies emerge from their pupa and spread their wings for the first time. Then Maddie heads to a wallpaper factory to learn how a repeat pattern is designed and the different colours are printed. She uses her special cameras to see how a printing machine uses rollers to print each separate colour and make the whole pattern repeat.
