mechanical equivalent of heat



Does anyone have a simple mechanical equivalent of heat laboratory
exercise (1st year undergrad level)?

I know of two; lead shot falling in a tube (which has horrible accuracy)
and the 'calorimeter on a crank' appratus (pretty costly). I don't like
either. Does anyone know of any others worth doing?
