Toward the end of World War II, Japan launched a strange new attack on the United States: thousands of paper balloons that would sail 5,000 miles to drop bombs on the American mainland. In this week's episode of the Futility Closet podcast, we'll tell the curious story of the Japanese fire balloons, the world's first intercontinental weapon.
We'll also discuss how to tell time by cannon and puzzle over how to find a lost tortoise.
