The ALS Ice Bucket Challenge has been going viral and has caught the attention of many celebrities. ALS (Amyotrophic lateral sclerosis) is also known as "Lou Gehrig's Disease,” which is a disease of the nerve cells in the brain and spinal cord that control voluntary muscle movement.

The challenge calls for someone, who was challenged by someone else, to pour a bucket of ice water over their head in support of the ALS association or to donate money to the cause. Celebs are doing the challenge in addition to donating money. See videos of the USA basketball team, Kevin Hart, Dwayne Wade, DeSean Jackson, Colin Kaeppernick and The Game.
