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.

Every time you wash your hands, you're using an amazing invention: the tap! That's why three budding scientists want to know: How do taps work? In this episode, Nicole, Kieran and Liam visit Nina in her workshop and see inside a tap.

Afterwards, they head off to a river to visit something big and twirly that uses the same science. With help from her neurons, Nina tells us about screws and shows us how to make our very own tap using some paper cups and lentils.
