Can you believe it's been a year since Taylor Swift , Chris Pratt, and more of your favorite stars got soaking wet for the ALS Ice Bucket Challenge? Well, Hugh Jackman  has just revived the phenomenon with his latest Instagram video. On Saturday, the actor shared a video of him pouring a bucket of ice over his head, marking the return of the sensation. Hugh captioned the video, "I know I'm late - but - THIS IS THE ALS 2015 ICE BUCKET CHALLENGE. #MND #ALS #AUS."
In case you want to get in on the comeback, here's how it works : people are nominated by their friends to go through with the stunt and share the video proof on social media. If they don't follow through, they're encouraged to at least make a donation. In the process, everyone raises awareness and money for the ALS Association  to find a cure for amyotrophic lateral sclerosis or ALS.
