What exactly is time? When Mum and Dad go away, seven days suddenly feel like an eternity – whereas the holidays fly by. Seven-year-old Stina wants to get to the bottom of it and sets off with her grandad on a fascinating journey of discovery. Together, they knock on all seven doors in their block of flats and discover that there are many answers to the question of time. Their journey takes them from a watchmaker, via an atomic clock expert, to a gardener and a physicist. Along the way, Stina not only learns about the fundamentals of physics, but also discovers how philosophy, culture and our own feelings shape the way we perceive time.
