From your friends to world-famous celebrities, it seemed like almost everyone was doing the ALS Ice Bucket Challenge. The point of the entire thing was to raise awareness and money for the ALS Association to find a cure for amyotrophic lateral sclerosis. The way it worked was simple: people nominated others to pour a bucket of ice over their head and share the video proof on social media. If they didn't follow through, they were encouraged to donate to the ALS Assocation.
The campaign, of course, went viral and inspired several other challenges, like the Plant a Tree For Groot Challenge. Watching people dump buckets of cold water over themselves was certainly entertaining, and even though it seemed silly, it still raised a whopping $115 million in donations.
