In today's episode, Maddie is having a party! She finds out how bubbles work when we blow into bubble mixture. She shows us how the surface tension of water changes when we add soap and how we can stop bubbles from bursting with our hands, and using her slow-motion camera, she shows how bubbles make a sphere shape. Next, Maddie heads to a factory where a party favourite is made - chocolate! We learn how chocolate starts out as a fruit, and we see the chocolates being made for an assortment box. Maddie also uses her special camera to see the super-fast robots that put the different chocolates into the right holes in their boxes.
