a great guy at SEMA whose booth had a fun game, try to be the closest to matching the pressure selected by spinning the wheel, with a vice and pressure gauge...

 trying to hit 5000 psi, or newton meters, or pounds feet... whatever the hell the unit of measurement was, I think I did fine for an utter newbie, I was 463 over. I think that's really good for SWAG how much to torque the vice.
