World Water Day on March 22nd is an ideal opportunity for NGOs to communicate about imbalances in access to drinking water across the globe. This year the theme is Water and Sustainable Development. In order to raise awareness and funds for the children of Togo, Unicef and Publicis Conseil turned to Twitter. The H2O Unicef Challenge will enable Twitter users to metaphorically “squeeze” the H, 2 and O out of their accounts. The newly created water molecules will be transformed into funds supporting access to fresh water at Togolese schools. In this way, Twitter will become the tool for spreading the word about the #h2ochallenge, as well as the means of taking part in the challenge itself
