To warn of the severity of Amyotrophic lateral sclerosis (ALS) and to contribute financially to its research. That is the main goal of an international campaign ALS Ice Bucket Challenge of which the Internet has informed the whole world. The idea of the Ice Bucket Challenge came from the USA; to fulfil the challenge participants pour ice-cold water over themselves, which should evoke a similar feeling of muscle stiffness that patients with ALS suffer from.
