But apparently his âsinkerâ made quite an impression on Warden. Like many other guys trying to hang on to a big league job, Ribant was clever in finding a way to get hitters out, conventional or otherwise. His âsinkerâ turned out to beâ¦the âspitballâ. Now the idea behind a âspitterâ is not some wet, gooey mess, but rather to create a âheavyâ spot on the baseball, thereby causing it to have greater wind resistance and sink dramatically when it gets to within a few feet of home plate.
When Benjamin Franklin invented his mechanical version of the instrument in 1761, he called it the armonica, based on the Italian word armonia, which means harmony. The unrelated free-reed wind instrument aeolina, today called the  harmonica , was not invented until 1821, sixty years later.
Thomas Edison created many inventions, but his favorite was the phonograph. While working on improvements to the telegraph and the telephone, Edison figured out a way to record sound on tinfoil-coated cylinders. In 1877, he created a machine with two needles: one for recording and one for playback.
