The Ice Bucket Challenge has become synonymous with gorgeous celebrities dousing themselves with water. There are many ways to raise awareness for various charities, but this has got to be one of the best!

Stars must agree, because they've been participating in huge numbers to raise awareness for ALS, also known as Lou Gehrig's disease. We previously did a roundup of 30 celebs who took part in the social media phenomenon, and now we're back to do another roundup to share some of the best videos.

For more information on ALS, how to donate and how you, too, can raise awareness, visit the ALS Association. And of course, check out the Ice Bucket Challenge vids below!
