Zara is an incredibly curious little girl. She loves learning about how things work and her super smart Gran is always on hand to answer her questions.

When they go for a walk to the shops Zara sees lots of interesting things which spark some in-depth conversations. How do lifts work? How can cranes lift such heavy things? How do roller coasters stay on the track when they go upside down? How do escalators run? What is wi-fi for? Her gran patiently answers each question with lots of detail to satisfy the little girls curiosity.

Gran also tells Zara about some famous engineers who have helped shape the world we live in, including Leonardo Da Vinci and Rahman Khan. Zara is particularly interested in the story of Alicia Boler-Davis whose childhood was very similar to hers. She loved problem-solving and fixing things as a little girl and went on to work as an Engineer at the General Motors car company.
