Maddie's Do You Know? S03 E01 Skyscraper and Flying Bird

Maddie finds out how really tall buildings are made out of steel and concrete. She visits a skyscraper construction site to explain how the concrete columns that are buried deep into the ground help to make it strong and stable. Then Maddie uses a special 360 camera to see all around her from the top floor. Next Maddie is finding out how birds fly. She visits a bird sanctuary and uses a special slow-motion camera to help us understand how Ollie the barn owl uses his streamlined body and powerful wings to take off, fly, and land.
