The UNICEF Tap Project was devised to educate people and have them help out in way that is so simple, they wouldn't even realize the change it would promote. The Tap Project explains that every minute you spend not using your mobile device an entire day of clean water will be matched from one of UNICEF's sponsors. This is pretty incredible if you ask me.
People are obsessive over their smartphone and tablets, so this is a challenge for some more than others. All you have to do is go to the project website and follow the directions. A lot of us don't realize how often we check our smartphones and how much time we really spend on them. This is a way for UNICEF to educate us on what we are missing and also provide for others. The combination is undoubtedly ingenious.
