Some pitchers can pitch a baseball at speeds upwards of 100 miles per hour. The fastest pitch recorded in Major League Baseball in the 21th century was pitched by Aroldis Chapman while playing for the Cincinnati Reds. The pitch was clocked at 105.1 miles per hour. In the video below, Destin, from the YouTube channel SmarterEveryday builds a baseball cannon capable of shooting baseballs at supersonic speeds (above 700 miles per hour). Back in 2001, former Diamondbacks pitcher Randy Johnson throwing a baseball at nearly 100 miles per hour disintegrated a bird that flew into it in a puff of feathers. Destin shoots the baseball at two inch thick sheets of steel, but you can pretty much imagine from the results what such a pitch would do to a baseball bat or a catcher!
