As a father, Hanna often asks me straight questions. Instead of being annoyed by the questions or getting rid of the child because of ignorance, we (Hanna and I) decided together to answer these questions as simply and plausibly as possible via podcast and thus keep the child curious and the general knowledge of all of us improve. This children’s podcast is a kind of radio play for children’s questions. We don’t promise children’s science here, but try to explain everything with common sense.
