If you're a fan of natural peanut butter, you're undoubtedly familiar with the fact that the oil always seperates and floats to the surface -- which is gross. This helpful peanut butter mixer will sort that out -- pronto. (via Popgadget)

Buying it now and I'll let you know how it works. Great idea but will the top fit?

The reason that I normally don't buy natural peanut butter is because I hate having to stir it every time I use it. The oil separates from the peanut butter and you stick your knife in there to try and give it a "quick" mix, but it's never quick and in the process you usually splash up the oil muck all around the sides of the jar and on the counter. All this makes you crabby when you eat your peanut butter sandwich. With this Mixer, all you do is pop it on the top of the jar, give it a few turns, slap it on some bread, and enjoy your sandwich with a smile! Super convenient! (via Amazon)

I just recently got into natural peanut butter because of its better nutritional value. The downside is the oil separation that requires you to sufficiently stir the peanut butter before eating. This is a hassle free mixer that solves this problem by screwing into any peanut butter jar. It allows you to effortlessly stir the peanut butter without any mess.

I have to say, I love organic peanut butter but I don't love how the oil separates out of it. I usually end up with most of the oil running down the jar. This fabulous little gadget would eliminate that because it stirs it all together again! Genius!
