What do you do when you only want to eat half of your can of Campbell’s Chunky soup or chili? You can use a Pringles lid to cover the can. Although it is a tight fit, it will ensure that the contents of the can do not spill.

FYI – One of the other uses I have found for Pringles lids is as a cheap Frisbee. With practice they can be bounced off of walls so that they go around corners with surprising accuracy.
