If you went on Instagram at all this weekend, you may have noticed that a ton of your favorite celebrities were dumping ice water on their heads — and for a good cause! The ALS Ice Bucket Challenge is a charity campaign that raises awareness for the the neuromuscular condition and has totally gone viral. Following the likes of Demi Lovato and Ansel Elgort, everyone from Selena Gomez to Austin Mahone have participated.
Here's how it works: A person who is taking on the challenge nominates up to five people to also participate. Once you're nominated you have 24 hours to make a video or you have to donate $100 to the ALS Association.
