Now you Know about Explorers is the latest in a series of DVDs which has already featured great world artists and scientists. Columbus, Vasco da Gama, Magellen and others get 10 minutes each. Fun cartoons, a refreshingly unannoying narrator, and my kids were hooked. How smug was I feeling when my daughter’s playdate’s mum came to pick her up? Telly vegging has never looked so good! £12.99
