Apparently heavy-metal moshers behave like gas molecules:
Mosh Pit Math: Physicists Analyze Rowdy Crowd : NPR
"... Using just a few variables, like how fast people moved and how dense the crowd was, Bierbaum and Silverberg created a mathematical model that they presented at this week's March meeting of the American Physical Society. Using a mixture of simulated moshers and standing fans, they could reproduce mosh pits, circle pits and other common collective motions that take place at metal concerts...."
"...The new mosh pit research could be interesting for another reason. In emergencies people panic, and the movement rules they follow change. Mosh pits might provide clues about the new rules.
"We hope that this will provide a lens into looking at other extreme situations such as riots and protests and escape panic," Bierbaum says."
The link includes a simulator.
