Maddie's Do You Know?

Umbrella and Carwash (2x2)

:

Today, Maddie is having fun with water. She takes a car through an automatic car wash to find out how the computer uses sensors to tell the robotic car wash how to wash the car, and she uses a special waterproof camera to see the big brushes in action. Next, Maddie heads to an umbrella factory to see how umbrellas are made using waterproof material. She uses a special slow-motion camera to show how the water droplets bounce off the waterproof material to keep us dry.
