The ALS Ice Bucket Challenge is taking Hollywood by storm!
Just to give you a little background, the challenge is a fundraising campaign for ALS (Amyotrophic Lateral Sclerosis) research, better knows as Lou Gherig's disease, a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.
To raise awareness, people are asked to participate and dare one another to get drenched in ice cold water within 24 hours, or they must donate cash to the ALS foundation. Those who decide to do the challenge are also encouraged to donate anyway.
