Maddie's Do You Know?: Camera and Hair Brush

SINOPSIS

Maddie finds out what happens when we have our picture taken. She shows us how the parts of a camera work to make the image bright and clear. With the help of a pinhole camera, Maddie learns what happens when light goes into the lens in order to take a picture. Next, Maddie heads to a hairbrush factory. We see how a hairbrush is made from big planks of wood. She uses her special cameras to see the robots turn the wood into a rounded brush handle shape at very fast speeds.
