Apples CEO Tim Cook is the latest notable person to undertake the Ice Bucket Challenge, and doused himself with icy water in the name of charity at a company event earlier today. The challenge was created to raise money for amyotrophic lateral sclerosis, better known as Lou Gehrigs Disease. So far, numerous celebrities and tech personalities have undertaken the challenge, including Apples marketing chief Phil Schiller, who posted a shots of himself getting doused on a beach today. As part of the challenge, you can either choose to donate or douse yourself with water, though many have done both.
