But will it be as big as the Ice Bucket Challenge? Well, all that water may have just made a real difference with some of the viral challenge donations helping fund a breakthrough in research into Motor Neurone Disease (ALS).
Researchers have just discovered a new gene associated with the disease and experts are hopeful it could lead to new treatments in future.
Brian Dickie, Director of Research Development at the Motor Neurone Disease (MND) Association said: "We are pleased to have been involved since this approach to gene hunting was in its infancy a decade ago.
"It's so encouraging to see how the collaboration, catalysed by Project MinE, has grown and is now delivering results that will open up new avenues of research across the world."
Earlier this year, the Power of Makeup challenge, which involves social media users sharing selfies that show half their face covered in makeup, went viral.
