The viral ‘Ice Bucket Challenge’ is back — this time, to raise awareness for a new chilling cause

In 2014, Americans were asked to pour buckets of ice water on themselves and post the video to social media in order to raise awareness for ALS, or Amyotrophic Lateral Sclerosis — commonly known as Lou Gehrig’s disease.

And they did — everyone from high schoolers to celebrities like Taylor Swift and Bill Gates got involved, resulting in a slew of viral videos.

The clips not only raised awareness of the progressive neurodegenerative disorder, but also raised about $185 million in the US alone — plus another $35 million worldwide.
