Time''s up / Canned food

When Buying food in a market, we often need to give an eye on the expiring dates. But everyday life is fast paced, and not everyone has the extra time to check the expiring date. So we asked ourselves: what if consumers could distinguish any food’s expiring date at first glance?
We wish to have a paint that would change color and become visible over time, just like the food’s expiring date.
