Some of the most powerful people in the tech world are dumping buckets of ice water on their heads. No, they haven't lost it. They're doing it for charity.
The stunt is a part of a campaign to raise money to fight amyotrophic lateral sclerosis (ALS), also known as the motor neurons disease. Those who take the ice bucket challenge get to challenge three other people to do the same within 24 hours or donate to the ALS foundation (hopefully, they'll do both!)
Zuck, who was challenged by New Jersey Governor Chris Christie, called out Bill Gates, Facebook COO Sheryl Sandberg and Netflix CEO Reed Hastings to take the challenge. You can watch him throw water over himself here.
Microsoft CEO Satya Nadella, who took the challenge before Zuck called out Amazon CEO Jeff Bezos and Google's Larry Page to follow suit. And Apple's Phil Schiller wants Tim Cook, among others, to get on board as well.
