The 2014 phenomenon returns to raise ALS funds and awareness, and Renee Zellweger and Justin Bieber are two of the first high-profile folks to douse themselves.
It's a movement that's taken social media by storm and has raised awareness for ALS (also known as Lou Gehrig's disease) along with more than $15 million since the Ice Bucket Challenge campaign started back on July 29th.
The #ALSIceBucketChallenge has swept through Facebook over the past couple of days as people are dousing themselves with buckets of ice cold water and bringing more awareness to ALS, more commonly known as Lou Gehrig's Disease.
