How to throw a spitball<br>Put a small amount of saliva or vaseline on the baseball. The object is to create resistance and a change in the uniform weight of the ball to make its motion more unpredictable and difficult to hit. There's no " right place " to put it, since the object is unpredictability, as with a knuckleball.

I did not use specific words from the text, just "liquid." It is correct because the text says "there is no right place to put it."
