The Fuse Ball

In 1926, Philip S. Kane of Pennsylvania received a patent for his "fuse ball" (Patent No. 1,583,721). It was a golf ball with a fuse. Before teeing off, you'd light the fuse, which would then start emitting smoke. That way, you could find the ball wherever you hit it, even if it landed in tall grass.

According to various media reports, while testing his ball Kane accidentally set a wheat field on fire, but I haven't seen any proof to back up that story.
