Peanut Butter is awesome!  It makes a great sandwich, awesome cookies, and even candy.  Heck, I like to eat a spoon of plain peanut butter for a snack sometimes. Peanut butter can be messy, especially if you have reached the bottom of the jar.  However, that may all change with this new invention.

The only bad thing about this,is it reminds me of a stick of deodorant.  The thought of stinky pits and peanut butter should never be combined.

I think it would work great for jelly, mayo, or even margarine.

What other products could you see in a jar like this?
