Construct an arsenal of mini-models of large launchers, based on siege weapons used throughout history. Wheel them out as you conduct a siege and load your catapults with raisins or marshmallows, and learn about history along the way.
Make a set of traps and triggers powered by rubber bands and inspired by real-life devices. Choose your target and area of operation, hide your traps and triggers, and wait. And learn about history along the way!
Make models of castles and little knights, and plan a medieval battle scene that uses the mini-launchers from other books in this series. Deploy your launchers, jump to your stations, and attack! And learn about history along the way.
"Send paper clips flying with your own miniature launcher! Step-by-step instructions are used in this book to demonstrate basic engineering and physics skills for kids."--
