Oh, the summer of 2014 -- what a time to be alive. It seems like only yesterday authentic rap goddess Iggy Azalea had two major hits on the radio, Sharknado got the sequel it rightfully deserved, and your Facebook news feed was clogged with endless videos of the Ice Bucket Challenge.
The social media stunt asked people to either donate money for ALS research, or dump a bucket of ice on your head (and also still donate to charity because what are you, a monster?), then challenge three friends to do it. So many people got in on the action, including Chris Pratt, Lebron James, Martha Stewart, and every single other celebrity alive.
If you were confused/annoyed at the time -- why were people assaulting each other with freezing water instead of just writing a check to charity? -- it turns out that so much ice and Facebook shares actually helped create a scientific breakthrough. The campaign ended up raising $115 million for the ALS Association. Two years later, scientists have used some of that money to discover a new gene, NEK1, which contributes to the disease.
