A Milk Carton That Changes Color When Expiring

Designer Ko Yang created a milk carton that changes color when expiring. The concept was that when milk rots, it turns to cheese. So when it gets closer to the expiration date, the carton turns from a white color to a cheesy design.

It's a neat design, because it provides a colorful way to remind you to drink the milk before it's too late.

You might be wondering now, where could I get these? This was created only as a design project and unfortunately won't be seeing store shelves anytime soon.

This is not the first time Ko Yang has created something unusual, because he also made this: (bit.ly/1XRldJ8).
