Potato-Based Lube

8 oz. cold water
4 tsp. potato starch

Whisk potato starch into water in a saucepan.  Bring slowly to a boil, whisking frequently.  Once the starch has reached a certain temperature, the starch molecules will burst, turning the whole conglomeration into a thick, viscous substance.  At this point, it’s done.  Be sure to allow it to cool before use!
