The Ice Bucket Challenge is an activity involving dumping a bucket of ice water on one's head, which was started as a campaign to promote awareness of amyotrophic lateral sclerosis (ALS), and gained widespread popularity in 2014. The rules state that after being challenged to participate in the activity, the challenged has 24 hours to either participate and donate $10 to the ALS charity of their choice, or, if they choose not to do so, to donate $100. This has led some commentators to criticize it for portraying the challenge itself as preferable to donating to ALS organizations. It has led to a significant spike in both funds raised for ALS-related organizations and awareness of ALS. Since July 29, more than 70,000 new donors have donated money to the ALS Association.
Some NBA players as JR Smith, Ben McLemore, Wesley Matthews and Moe Harkless participated in the game.
Mark Zuckerberg too participate in the campaign.
