Mark Zuckerberg Takes Ice Bucket Challenge

Facebook founder Mark Zuckerberg took part in the ALS “Ice Bucket Challenge” on August 13. The challenge, which has been taking the internet by storm, sees people pour ice-cold water over their heads in an effort to raise awareness about amyotrophic lateral sclerosis. Participants then nominate a friend to do the same.
