If you've been on social media at all lately (or just the internet in general), you couldn't miss the latest trend even if you tried: Dumping a nice, big bucket of ice-cold water on your head. Sounds refreshing, right? All our favorite stars are doing it, from TFIOS's Ansel Elgort to Pitch Perfect's Elizabeth Banks. But why are they filming themselves doing such a crazy thing? It's for a good cause, promise.
The Ice Bucket Challenge was started for one reason: To raise awareness of ALS, also known as amyotrophic lateral sclerosis, which is a disease that affects nerve cells in the brain and spinal cord. When you get nominated to do the challenge (by someone who's just done it themselves—it's a pay-it-forward situation) you have 24 hours to do one of two things: Either pour ice water on yourself, or pony up and donate $100 to the ALS Association Research Program.
Some people do the dare part, but a lot of celebs have stepped up to do both. And watching it all go down? Priceless. Check out our favorites below!
