The Fault in Our Stars and Divergent actor Ansel Elgort has officially completed the ALS ice bucket challenge.

The ALS ice bucket challenge is a fun way people have been using social media to create awareness and raise funds to fight Lou Gehrig's Disease. According to alsa.org, Amyotrophic lateral sclerosis is a neurodegenerative progressive disease that affects muscle coordination and eventually leads to total paralysis.

The ALS ice bucket challenge is a movement that has swept the Internet by storm. Essentially, people are given 24 hours after receiving their nominations to dump a bucket of ice water over their heads or donate $100 to the cause. Most people both donate and do the bucket challenge before nominating their friends to do the same.

Hollywood heartthrob Ansel Elgort has joined the movement as well. He posted two videos on Instagram—one announcing his nominations and the other dumping the bucket over his head. Elgort predictably nominated TFIOS costar Nat Wolff and author John Greene. However, he also challenged Teen Wolf’s Dylan O’Brien.
