Study Highlights Unique MLB Rubbing Mud Properties

A new study has shed light on the unique properties of the 'magic' mud used on Major League Baseballs, known as Lena Blackburne Baseball Rubbing Mud. This mud, sourced from a secret location in New Jersey, has been a staple in the MLB since 1938 to improve ball grip by reducing slickness. Researchers from the University of Pennsylvania published their findings in the Proceedings of the National Academy of Sciences, detailing that the mud spreads like face cream but grips like sandpaper. The study highlighted the mud's composition, which includes a mix of clay, sand, and water that increases adhesion and friction on baseballs. Despite various attempts, no suitable synthetic alternatives have been found to replace this natural mud. The research not only confirms the mud's efficacy but also opens possibilities for applications in sustainable material development.
