Time for Cogs

Nina looks at different household inventions and finds out how they work. With the help of her trusty neurons she examines the items to answer children's questions.

Clocks are such a useful invention that Boston, Cooper and Jay ask Nina How does a clock work? With a little help from beautiful Belle, Nina invites the three friends to her workshop to find out more.

Once they've had a good look inside a clock they head off to see an amazing invention that can lift up boats using the same science. If you want to learn all about cogs and find out how to make your own using cardboard and a bottle top, then tune in to today's episode of Nina and the Neurons Go Inventing!
