Heureka's Christmas calendar
In this year's Christmas calendar, you can read the story of two children who are looking for Heureka's science rat. Will they find it before Christmas? There will be adventure at Heureka's exhibitions, science tasks and lots of learning something new.
In each chapter, you can read a short clip from the story. The story continues every day until Christmas. It is a feel-good Christmas story that you can, for example, read together with your child. In each section, you can also participate in a lottery by answering the question of the day.
You can follow the Christmas calendar on Heureka's Instagram. The story is in Finnish.
