The Ice Bucket Challenge, sometimes called the ALS Ice Bucket Challenge, is an activity involving dumping a bucket of ice water on someone's head to promote awareness of the disease amyotrophic lateral sclerosis (ALS) and encourage donations to research. It went viral throughout social media during July-August 2014. In the US, people participate for the ALS Association, and in the UK, people participate for the Motor Neurone Disease Association.
The challenge dares nominated participants to be filmed having a bucket of ice water poured on their heads and challenging others to do the same. A common stipulation is that nominated people have 24 hours to comply or forfeit by way of a charitable financial donation.
