Nothing is worse than being unsure if the food you're about to consume has or is about to go bad, but thankfully this 3D-printed food cap by UC Berkeley will be able to alert you to when your milk has spoiled.

Thanks to the research team at UC Berkeley, there is a milk carton design that comes with smart caps that are able to detect the bacteria in spoiled milk. Users can then shake the milk around in the carton enough so that the milk splashes on the backside of the cap and wait to read the indicator on the outside. The indicator will let you know if the milk has spoiled or is still fresh to drink. This innovative design will eliminate the need for guesstimated expiry dates listed on milk packaging.
