Korean teenagers drink a lot of beverages instead of water and are ranked first in the world for obesity. We asked 'why didn`t you give water to your children instead of beverages? Is it because no one ever showed you that it`s good to drink water?' That is why we decided to perform a seemingly impossible experiment to upend this dire situation. With an uncontrollable 56 students of 14 years old, an experiment to abstain from beverages and drink 8 glasses of water every day for 6 months. Let the world see changes by water. 'Let our children drink clean water!'

Water purifiers were installed in front of every classroom. Children kept daily water logs through website and mobile application and medical check-ups were performed regularly to identify physical and mental changes. Those who had drunk the most water were awarded every month for the children`s motivation.

Within a month after the first TV commercial, more than 10,000 supporting messages were uploaded on the newly launched website. The films were shared more than 20,000 times and the press started to cover the severity of beverages and the positive effect of water. As a result, the sales of fruit drinks and energy drinks fell more than 20% and the sales of bottled water continuously increased. The sales of water purifiers significantly rose and COWAY recorded the highest sales since its founding. Above all things, people who had seen this seemingly impossible experiment got to know what our children should drink: The clean water!
