I've heard a lot about the ALS ice bucket challenge. What's the story?

The ALS Ice Bucket Challenge is a social media campaign that has been used to raise awareness of ALS, also known as Lou Gehrig’s disease. People are challenged to either donate money to research or to pour a bucket of ice-cold water over their heads and post a video of themselves doing it on social media. The goal is to get people to spread the word about ALS and encourage donations to help find a cure for this devastating disease.
