Watch Videos The Ice Bucket Challenge, sometimes called the ALS Ice Bucket Challenge, is an activity involving dumping a bucket of ice water on one's head or donating to the ALS Association in the United States. It went viral throughout social media during the Northern-Hemisphere summer of 2014.
The challenge dares nominated participants to have a bucket of ice water poured on their head. One common stipulation gives 24 hours from the time they are nominated to complete the dare; otherwise, the participant is asked to donate money to charity.
The origins of the idea of dumping cold water on one's head to raise money for charity are unclear and have been attributed to multiple sources. During the Northern-Hemisphere winter of 2013–14, a challenge of unknown origin often called the "Cold Water Challenge" became popular on social media in areas of the Northern United States. The task usually involved the option of either donating money to cancer research or having to jump into cold water. It was criticized for the danger of going into cold water unassisted. by wikipedia.
