Leave it to those clever folks at UNICEF. Last month they launched the “Tap Project,” which challenged people to put down their smart phones — as in not touching ‘em, not even just to send this one little text — for a bit. For every five minutes participants could hold out, Giorgio Armani Fragrances and S’well pledged to provide the funding equivalent of one day of clean water for a child.

It was tough but well worth the “sacrifice”: Over 400,000 people went phone-free, which translates to over 440,000 days of clean water that UNICEF will be able to bring to children in more than 100 countries around the world.

And now they’re back with an even easier way for you to help kids. Or is it harder?

Actually, it doesn’t matter. All you have to do is take a six-question quiz at www.unicefusa.org/take-the-quiz and those same two sponsors will donate 50 cents in your name to UNICEF’S efforts.

The questions have to do with malnutrition, immunization and other incredibly important issues involving the world’s children. So even if, like a certain unnamed and not-very-bright reporter, you only answer two of the questions correctly, “You probably learned a lot,” as UNICEF sweetly and accurately pointed out.
