Unraveling the Mizugumo Mystery

This chapter explores the historical device Mizugumo from a 17th-century ninjutsu manual, traditionally believed to allow ninjas to walk on water. The discussion includes a scientific examination of buoyancy and surface tension, ultimately suggesting it may have served as a flotation seat rather than functional footwear. Through critical analysis and informal tests, the chapter invites listeners to consider the practicality of ancient devices versus modern transportation methods.
