Double Dangerous Book for Boys (Hardcover Book)

President Teddy Roosevelt said that boys should study hard and play hard—and this Double Dangerous Book for Boys provides even more tools to help boys (and girls) to respond to that command. A continuation of the first Volume, Dangerous Book for Boys, this book is full of fascinating information answering questions about our world, explaining historical events (such as the navigation of the ancients to the Mars lander); learning skills like playing games and tying a tie; or learning about mathematicians from Pythagoras to Stephen Hawking. Learn how to solve a rubrics cube, create a stress ball, or identify common American trees, and more. The breadth and interest of topics is captivating, but you’ll want to be aware that this comes from a secular UK, publisher (so you’ll find some unique British wording such as, “casting a clout” and metric measures). While most topics are neutral, there is an in-depth discussion of how to pick a lock (check your state laws on lock picking); how to make a stink bomb; and how to make an elastic-band gun.
