The ALS Ice Bucket Challenge has turned into a viral sensation in major social networking sites. Countless celebrities have dumped a bucket full of cold water and actual ice on themselves as a statement to support ALS.
Exactly how does this challenge move from one person to another? When a person receives the challenge, he or she has to do one of two things: take a video of himself or herself being dumped with water or donate $100 to the ALS foundation.
If the person is generous enough, he or she can do both.
After following through with the task, the person then passes on the baton to his or her friends.
The viral event also gave way for people or celebrities to name drop other famous friends.
Thor's Tom Hiddleston, for example, nominated his buddy, Benedict Cumberbatch, while Taylor Swift challenged her newly reconciled BFF Selena Gomez.
Justin Bieber threw ice on himself twice. On the other hand, Charlie Sheen opted to throw money on himself rather than water.
