The campaign idea for drench bottled water is: ‘Brains perform best when hydrated. Stay drenched.’Goldfish are renowned for having an incredibly short memory – arguably a recollection of the last seven seconds.So we created Mr Memory – a goldfish with an incredibly long memory. And how better to dramatise his mental powers than in a watery mental assault course. Filled with drench bottled water.Successfully remembering numbers, knowing which part of a Ferris wheel to swim in to, and recalling where a ball has been hidden under a cup, Mr Memory proves that by staying topped up with drench water you can keep your brain hydrated so that you can perform at your best.
