Bike Bell and Line Markings

Maddie's Do You Know? - CBeebies - BBC

Maddie learns how bike bells make a ringing sound and how line markings are made.

Maddie visits a bike workshop to learn about how bike bells work and how they make different sounds. Afterwards, she heads to a rugby stadium to discover how line markings are painted.

Maddie is on her bike! She visits a bike workshop to find out why different bike bells make different ringing sounds. Maddie uses her special slow-motion camera to see inside a ring bell so we can see how something called a beater spins around really quickly, hitting a bump called the butt to make a long ringing sound.

Next, Maddie visits a rugby stadium to see how line markings are painted onto the pitch so that the players know where to play. Maddie attaches one of her special cameras to a line marking machine to see how it uses a sensor and a nozzle to keep the lines really straight!
