Maddie's Do You Know?
Lock and Key, and Glass
S1 • E15 Oct 24, 2016
Maddie explores the house. She uses a special camera and animation to see how a key works inside a lock and shows how the hidden barrel and pins inside the lock work, to allow the matching key to unlock it. Next, Maddie shows how sand is made into glass. She visits a glass-blowing workshop to see how sand is turned into molten glass and then worked by the glass-maker into a brightly coloured glass vase.
