How does a spitball effect the flight of a baseball? What kinds of substances can you put on a baseball to make it a spitter? Why are they illegal?

Because of the forces involved in a curve ball, Magnus force, the rotation of a "spit ball" becomes quite unpredictable and dangerous to the batter-hence they are illegal. For a detailed description of the forces go the book on the Physics of Baseball by ???, forgot his name but he is from Yale's Physics Department.
