A milk that notifies you when it expires


Via Microsiervos we found out about a very curious invention.

The designer of this idea is called Ko Yang, it consists of bricks that change color as the expiration date of the milk they contain approaches.

The truth would be quite practical… imagine that the same carton will indicate how long it takes for the milk to expire! In my opinion, a rather creative and original idea.
