Peanut butter hack — use a massage gun

After seeing a video of someone using a massage gun to force every last drop of mayonnaise out of a bottle, I decided to try in on a plastic jar of unmixed natural peanut butter. I pushed the business end of the gun against the side of the jar and marveled at how quickly the vibrations mixed the separated oil with the solids. A week later, the peanut butter remains perfectly blended. Note: I've only tested this on plastic jars; use caution with glass containers. — MF
