Many celebrities, sport personalities, and other well-known figures are taking part in the ice bucket challenge to raise public awareness for the Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, an illness which affects the nerve cells in the brain and spinal cord that control voluntary muscular systems within the body. Charting the success of the ALS ice bucket challenge craze that have been sweeping social media channels by storm, we have round up the best of the best, in no particular order.
