Two Quarter Pressure Regulator Mod [technique]

I learned this from the Shroomery, but wanted to share here for anyone who might not know about it. If you're using a modern Presto pressure canner, attaching two quarters (US) to the top of the pressure regulator will add just enough weight to keep it still at 15 PSI, while still allowing it to rock before reaching unsafe levels. With this setup there's minimal steam loss, you can maintain pressure with a lower burner, and it's SO MUCH QUIETER. Total game changer.
