Four Wire Kelvin Resistance Measurement

I can't afford a fancy benchtop multimeter with 4-wire measurement capability, so I made a current source and will show you how to make an accurate low-resistance measurement with this setup. There's a cool water-circuit that shows how current flows in a 4-wire system which turned out a lot cooler than I thought it would. Hope you guys enjoy!
