LifeHack: Easy tip for stirring natural peanut butter that has settled in the jar

Ever notice that the natural peanut butter you like can be very hard to stir

and mix after it has sat on the supermarket shelf for a while?

You can have an inch of oil floating on hardened peanut butter

which is the consistency of concrete.  

You get "tennis elbow" just trying to churn that stuff up and stir in the oil.

Here's a tip: just park the jar in the kitchen and, once a day, as you pass by,

flip it over.

This worked so well for me that I brought the idea into work, submitted a patent application

for a motorized version, and IBM gave me a patent award for it!
