Valser is one of Switzerland's most famous mineral waters. Every bottle comes from one source and every drop spends at least 25 years traveling through a single mountain that's a Kilometer deep. When Coca Cola asked us to re-launch the brand, we decided to position the mountain as the oldest, deepest and slowest water processing plant in the world. Then we developed the world's deepest website (a digital kilometer) to let visitors take their own 25-year journey through the heart of the mountain. All our communications were built around the line "Valser nimmst sich seit" which means "Valser takes it's own time". We were contacted soon after we finished by several high school geology teachers. Eventually the site was officially included as part of the Swiss secondary school geology curriculum.
