CHICAGO (CBS) — As if the world needs another reason to adore Matt Damon, the actor and activist took the ALS Ice Bucket Challenge, but with a twist, using toilet water collected from around his home.

Damon, who co-founded, says he made the substitution to bring attention to the approximately 800 million people around the world who do not have drinkable water. “The water in our toilets in the West is actually cleaner than the water that most people in the developing world have access to,” he claims.

According to its website, “is a nonprofit organization that has transformed hundreds of communities in Africa, South Asia, and Central America by providing access to safe water and sanitation.”

Damon ends the short video by nominating George Clooney, Bono and Tom Brady for the ALS Ice Bucket Challenge. Let’s see if those guys will be just as creative.
