This jar of exploding mayonnaise serves as a reminder why one should pay attention to the “sell-by” dates on the sides of packages. Submitter Doug writes:
Yesterday my mother went to open a new jar of Stop and Shop light mayonnaise. After she unscrewed the cap the contents started bubbling out from under the seal. She removed the seal and the result is what you see here. We took it back to the store, where they apologized and replaced it with the non-exploding kind.
You can see in the picture that the jar is six months past its sell-by date. UPDATE: Oops, we’re stupid, that’s the year 2008. Damn, there’s no reason for this mayo to go unless maybe that’s a misprint. Why would it explode, though? Bacteria get inside and cause a gaseous buildup? We’re betting heavy on “compromised seal.” Full-size pics inside…
OMG MAYO GO BOOM!
