She finds out how satellites high up in space can see the clouds moving and tell us when it might rain. Next, Maddie visits a radiator factory to find out how radiators are made to keep our houses warm. We see how big flat sheets of metal are pressed to make grooves, like teeth. The metal pieces are heated up and sealed together to make sure the water doesn’t leak out.

She goes inside to where the bulb is kept and finds out how all the reflective glass that surrounds it helps make the light stronger. Then she uses a special drone camera that flies out to sea! The drone camera shows us how strong the light bulb is because it needs to warn ships miles out to sea that there's shallow water or rocks nearby. Next, Maddie visits a factory where bath bombs are made to find out about the ingredients that make bath bombs fizz! She discovers why it’s called a chemical reaction. Maddie uses her special underwater camera to show us the fizzy bubbles that are made when the bath bomb is dropped into water.
