Ok, foam on water is close enough then I imagine. Cheaper than ball bearings/aluminum channel too. A touch of soap to break surface tension maybe?

For 'load cell', could a .001g scale flipped vertically work? Have a loop of wire go to the center of the scale and you could measure that way?

Way cheaper than the $1350 load cells I was looking at...
