Break the Siege by Rob Ives
What kids has never wanted his own catapult? This book makes it fairly easy for that desire to become a reality. The instructions are clear with plenty of illustrations for clarification. Materials are everyday items, meaning that any of the devices in this book are within the grasp of the average reader. There is a little historical background for each siege machine, so it has some education value as well. A great choice for most upper elementary kids.
