In case you never heard it, I am an agriculture engineer and an environmental economist. So basically, yes, I know my biology and my science. Which brings us to Nestle Purelife. The ad is huge, very huge. It portrays the whole panoply of shapes and forms in which Nestle Purelife comes. Good for them. I mean, how creative can you get when your brief it to show the different sizes? So the ad at least is orderly, nice, and of course, blue. It is however their line that caught my attention. "Hydrate your body. Refresh you mind." Now the first part is a no-brainer. But Nestle has its lawyers looking at every comma of their ads, which is why "refresh your mind" caught me off-guard. What does it mean? Technically and on-the-ground? Is it a play on words? Can it stand on its own legs in terms of a promise? Once more, knowing how involved the lawyers of Nestle are, I wondered how this one seeped through the net.
