Children are full of curiosity and questions about the world. Each Friday, join Molly Oldfield, the very first question writer (or QI Elf) on the BBC TV show QI and author of three books, as she answers questions - often with the help of experts - sent into the show by children around the world. If you're a kid with questions you want answered or if you want to learn interesting facts about life on earth, this is the podcast for you.
