Sasol Milk Bottles

This new Sasol ad proposes 'intelligent' milk bottles with a colour-changing indicator for when the milk goes sour - and only in the closing seconds do we see that it's a Sasol ad about the importance of innovation. Very clever, very watchable, but for me the innovation message gets lost versus the novelty of the bottle idea.

Call me overly literal, but I reckon there's a lot of people out there who are trying to figure out where they can buy the bottles...!
