Last but not least: ear torture at its finest
You're probably familiar with the sound made when you run your fingernails across a chalkboard. It's awful! Ogilvy Mumbai created a commercial for Mentos that consists almost entirely of that sound.
The sound sends shivers down your spine and makes all your body hair stand on end, and you just want it to stop. And immediately. Dedicating an entire commercial to this ear torture, as Ogilvy Mumbai did for Mentos, is a little, shall we say, daring. But it makes sense - at least a little, perhaps. The agency's succinct explanation on the YouTube channel for the commercial reads: "Mentos Sour Marbels are sour, really sour". So much for a clue. It's best to form your own opinion as to whether the commercial encourages you to chew on Mentos or has the opposite effect.
