Science?

Cornell grad students and professors have shown that the behavior of metal heads in a mosh pit is very similar to the motion of gas molecules including not just the randomness but behaviors such as a circular vortex and lane formation.

So the next time you go see Lemmy and Motorhead you can write it off as research.

    I may just be old, but I think I am proud I don’t know who “Lemmy and Motorhead” are!

    • Steve, you might not know Motorhead because you’re young! 😉 Motorhead goes back to the late 70s and Ian Fraser “Lemmy” Kilmister is the lead singer. (Yup, I listened to them while growing up 🙂 ) I gather he’s still alive and playing. LOL, I’m trying to picture John with long hair and headbanging.

      John, liked the bit about the cylinder. Well, I liked everything.

    I suppose we could find a country line dancing study but that might be more about crystallography than gas dynamics.

    Thanks for the reminder, Darrin.
