Maddie is at the coast! She visits a red and white striped lighthouse and meets the lighthouse keeper right at the top. 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.
