What makes baseball’s “magic mud” so special?

It has just the right mix of spreadability, stickiness, and friction to give pitchers a better grip on the ball.

Since the 1940s, baseball players have been spreading a special kind of "magic mud" on new baseballs to reduce the slick, glossy shine and give pitchers a firmer grip. Now, scientists at the University of Pennsylvania have identified just what gives that magic mud its special properties, according to a new paper published in the Proceedings of the National Academy of Sciences.

Before magic mud came along, baseballs were treated with a mix of water and soil from the infield or, alternatively, tobacco juice or shoe polish. But these substances stained and scratched up the ball's leather surface. Lena Blackburne was a third-base coach for the Philadelphia Athletics in the 1930s when an umpire complained about that, so he hunted for a better mud. Blackburne found that mud in a still-secret location purportedly near Palmyra, New Jersey, and a baseball dynasty was born: Lena Blackburne Baseball Rubbing Mud. Once harvested, the mud is strained, skimmed of excess water, rinsed with tap water, and then subjected to a secret "proprietary treatment" before being allowed to settle.

Yet there hasn't been much scientific research on the magic mud apart from one 2022 study. We do know quite a bit about the complex behavior of soil in general, including mud. Per the authors, mud is essentially "a dense suspension of predominantly clay and silt particles in water," sometimes with a bit of sand in the mix, although this has little effect on how mud behaves under shearing forces (rheology). Technically, it falls into the non-Newtonian fluid category, in which the viscosity changes (either thickening or thinning) in response to an applied strain or shearing force, thereby straddling the boundary between liquid and solid behavior.

Recap: Our “AI in DC” conference was great—here’s what you missed

Experts were assembled, tales told, and cocktails consumed. It was fun!

Ars Technica descended in force last week upon our nation's capital, setting up shop in the International Spy Museum for a three-panel discussion on artificial intelligence, infrastructure, security, and how compliance with policy changes over the next decade or so might shape the future of business computing in all its forms. Much like our San Jose event last month, the venue was packed to the rafters with Ars readers eager for knowledge (and perhaps some free drinks, which is definitely why I was there!). A bit over two hundred people were eventually herded into one of the conference spaces in the venue's upper floors, and Ars Editor-in-Chief Ken Fisher hopped on stage to take us in.

"Today's event about privacy, compliance, and making infrastructure smarter, I think could not be more perfectly timed," said Fisher. "I don't know about your orgs, but I know Ars Technica and our parent company, Conde Nast, are currently thinking about generative AI and how it touches almost every aspect or could touch almost every aspect of our business."

Fisher continued: "I think the media talks about how [generative AI] is going to maybe write news and take over content, but the reality is that generative AI has a lot of potential to help us in finance, to help us with opex, to help us with planning—to help us with pretty much every aspect of our business and in our business. And from what I'm reading online, many folks are starting to have this dream that generative AI is going to lead them into a world where they can replace a lot of SaaS services where they can make a pivot to first-party data."
