Maddie's Do You Know?

Magnets and Teddy Bears (1x21)

Data di messa in onda: Ott 31, 2016

Maddie is looking at toys. She uses a special slow-motion camera to find out how the magnets on a train set work. An animation shows how the north and south poles on magnets work and why a magnetic field can pull magnets together or push them apart. Next, Maddie visits a factory to see how teddy bears are made, with eyes, ears and joints, and uses a special microscope camera to see the fibres of the stuffing.
