Some people are going and dumping a bucket of ice water so that they don't have to donate money to a good cause. The ones that are picked to do the challenge has 24 hours to complete the challenge or pay up. http://mda.org/disease/amyotrophic-lateral-sclerosis?iq_id=70605352&source_code=140802AAAC030710-VQ16-c  http://www.cleveland.com/healthfit/index.ssf/2014/08/the_disease_behind_the_bucket.html . I don't believe its helping if people are just dumping water over someone's else's head. I believe they have the right idea at least they are trying to help. I believe if you get nominated  twice then you should pay a small donation. But as long as people are trying to help others that are in need then I'm fine with it.
