Roger Clemens helps Jamie and Adam test whether a corked bat can hit a ball farther than a regulation bat. Meanwhile, the others investigate the impact of humidity on a baseball's velocity and distance. Roger and a NASA researcher demonstrate how air pressure and force affect pitching and the team experiments to find out if sliding into a base is faster than running to it. Finally, Adam and Jamie test to discover if it's possible to knock the hide off a baseball.
