Not even the top CEOs in the tech industry could resist participation in the Ice Bucket Challenge.
The viral challenge, where people dump a bucket of ice water over their head, kicked off earlier this year, and is helping to raise awareness for ALS, known as Lou Gehrig's disease. Once completed, participants then challenge three others to either do the same or make a donation to the national ALS Association.
On Wednesday, New Jersey Governor Chris Christie completed the Ice Bucket Challenge, and urged Facebook CEO Mark Zuckerberg to follow suit.
Zuckerberg accepted. "That was really cold," he says after soaking himself with a bucket of ice water. Zuckerberg also selected three people to take on the challenge: Microsoft co-founder Bill Gates, Netflix CEO Reed Hastings and Facebook Chief Operating Officer Sheryl Sandberg.
Meanwhile, Twitter CEO Dick Costolo took the plunge (or the dump, in this case). Bonus points for the branded t-shirt.
Also participating: Microsoft CEO Satya Nadella, who went big with his nominations to take on the Ice Bucket Challenge: Amazon CEO Jeff Bezos and Google CEO Larry Page.
The Ice Bucket Challenge has had a big impact on ALS awareness in a very short time. Since late July, the ALS Association has raised $2.3 million.
