TSA classifies peanut butter as a liquid, restricts amount on flights.

The TSA has redefined physics to their liking, allowing frozen liquids to be brought through security checkpoints, but classifying peanut butter as a liquid due to its ability to conform to its container. The agency limits liquids to 3.4 ounces per container, but does not call in a hazmat team for larger amounts, instead combining them in a bin next to passengers and employees. The agency's confusing rules and language fail to match their behavior.
