I would like to ask you all a question: what is flat and black and can move up to 100 miles per hour? If you answered a burnt cookie on a jet plane you and I are on a different wave length. But if you answered a hockey puck, you're ready for my speech. Honorable judges, teachers, fellow students and guests. Today, I would like to talk to you about hockey pucks.
In the early days, hockey players didn't care what they used for hockey pucks. They would often use a piece of wood, a piece of coal , or even, get this, a piece of manure! But after many years they started using a ball similar to the lacrosse ball.

22 minutes later the puck comes out with dimpled...
