The summary is:
Two friends try to break a baseball by catching it repeatedly with pitching machines. They document the changes in the ball, the gloves, and their own reactions over the course of 12,101 throws and three months. They encounter various challenges and surprises along the way, such as losing visibility, hurting their hands, and making the ball move unpredictably. They eventually give up when the ball becomes too dangerous to catch, but not before having some fun and learning some science.
