This is the last Ice Bucket Challenge video you'll ever need to see: a hypnotic visualization of one of the biggest viral philanthropic phenomenons ever.
This video uses data from Google Trends to show how quickly the challenge spread across the globe. The 30-day period represented in this video, from August 7 though September 6, shows the trend reaching peak virality in the United States and many other countries, as well as the beginning of its fade into meme history.
