Just today, we reported that Mark Zuckerberg challenged Bill Gates, Sheryl Sandberg and CEO, Netflix, Reed Hastings to the Ice bucket Challenge for the ALS Foundation.
Well Bill Gates seems to be the first out the three to accept his challenge.
Check out his video below and he challenges Elon Musk, Ryan Seacrest and Chris Anderson from TED to do the same.
Here is Bill Gates on his twitter page after the event.
Brrr! I dumped ice water on my head to raise awareness for ALS. Over to you, @ryanseacrest, @elonmusk, and @TEDchris http://t.co/ZzqmhkGbMS
