What is a tiny hole below the thumb on a bowling ball for?
In tenpin bowling, bowlers who are having difficulty with release, usually related to the ball sticking on the thumb, will sometimes have a very small hole drilled just below the thumb hole, at angle that enters into the lower part of the thumb hole. This is to allow air into the lower region of the thumb hole and prevent a vacuum from taking hold.
