The ninja, though, had much more than tools and weapons in their arsenal. They also employed a wealth of wisdom and skills through disciplines such as psychology, pharmacy, medicine, astronomy, sorcery and divination. A ninja could create a compass using a needle or a thin metal strip or tell time by reading the sky. They also knew several ways to find water while out in the field on a mission. It is through the ninja's resourcefulness and strategic and tactical thinking that the museum attempts to teach visitors survival skills that apply even in the modern world.
