Pinewood Derby Lubricant Testing

Doing searches for pinewood derby lubricants on Google or eBay will yield lots of results.  You will likely find statements such as:

– “Tungsten Disulfide (WS2) has an coefficient of friction lower than that of Teflon, Graphite, or Molybdenum Disulfide”
– “Molybdenum Disulfide (MoS2) has a coefficient of friction less than graphite. ”

That such sound intriguing, but if make sure you dig deeper into the details before succumbing to the marketing hype.

This article in Pinewood Derby Times Volume 8, Issue 10 takes a closer looks at TS2 and MS2.
