In times of Google and Wikipedia, knowledge is infinitely available online, yet it remains increasingly inaccessible or uninternalized for many people. We only integrate knowledge when we connect it with emotions. And for that, a children's story is simply the best fit. Mercury visits his planet friends, and through this, we get to know the planets of our solar system. It's a successful bedtime story that can be expanded in countless ways and stimulates the imagination. Perfect for curious little explorers, as well as for all dreamy star seekers.
