Ages 5 to 12 years. Kids can re-create a long-ago world of kings, castles, jousts, jesters, damsels, magic fairies, and Robin Hood -- all they need are their imaginations, materials they can find at home, and the activities in this book. Dressing up in a coat of armor made from plastic milk jugs, whipping up a batch of curds and whey, writing secret messages in invisible ink, and telling time with a sand glass made from soda bottles are just some of the fun projects. Every activity is illustrated, and sidebars highlight colorful facts about life hundreds of years ago.
