'Ice Bucket Challenge': Mark Zuckerbeg, Bill Gates, Selena and Others Accept it [VIDEOS]

The "Ice Bucket Challenge", an activity to raise funds and awareness about Amyotrophic Lateral Sclerosis (ALS),  has gone viral all over internet but for a right cause. ALS is a disease which attacks the nerve cells leading to paralysis, though mind remains active.

In the "ALS Ice Bucket Challenge", a person has to make a video of him dumping a bucket full of ice water on his head and post it on Instagram or any other social media sites. The fun adds when the person has to challenge their friends to do the same within 24 hours or donate $ 100 to ALS.

From 'Selena Gomez ' to 'Justin Timberlake' and from 'Bill Gates' to 'Mark Zuckerberg', the face-off of pouring a bucket of ice on one's head has been accepted by many celebrities and businessmen.

The "Ice Bucket Challenge" has raised $ 22.9 million in donation as of 19 August, according to the official website of ALS association.

"Our top priority right now is acknowledging all the gifts made by donors to The ALS Association," said Barbara Newhouse, President and CEO of The ALS Association.

"We want to be the best stewards of this incredible influx of support. To do that, we need to be strategic in our decision making as to how the funds will be spent so that when people look back on this event in ten and twenty years, the "Ice Bucket Challenge" will be seen as a real game-changer for ALS," she added.
