KUSA - After Mark Zuckerberg challenged Bill Gates to dump a bucket of cold ice water on his head, he delivered.
The 58-year-old billionaire responded by having the water dumped from a contraption he could control.
"I'm always up for a challenge.Now I'm passing it on to On Air with Ryan Seacrest, Chris Anderson from TED, and Elon Musk. You have 24 hours," Gates said on his Facebook page.
The money raised from the challenge goes to help ALS research.
