VIDEO: Mark Zuckerberg Ice Bucket Challenge Done; Nominates Bill Gates

The Ice Bucket Challenge is getting popular these days. Billionaire and Facebook founder Mark Zuckerberg has become the latest big name to pour a bucket of freezing iced water over his head in the name of charity – and has challenged Bill Gates to be next.

Zuckerberg took part in the Ice Bucket Challenge, which was launched by the ALS Association to raise money for fighting ALS, also known as Lou Gehrig’s disease.

He then nominated Bill Gates, Sheryl Sandberg and Reed Hastings to do the challenge next.

The Ice Bucket Challenge has raised more than $4m for the ALS Association since July 28.
