So for those of you who are unfamiliar, the #IceBucketChallenge is a viral challenge that asks you to either A.) Donate $100 to ALS (Lou Gehrig's disease) or B.) instead of donating, dump a bucket of ice water over your head, then nominate three different people you know to take the "challenge" and go through the same process as listed above (steps A & B).
In my opinion, more people are spending money on ice and buckets versus actually donating to ALS. 

Either way, celebrities have embraced the concept and it is trending world-wide.  Also it's not harming anyone either!  :)  
I hope you enjoy this video of, "The Fault in Our Stars" co-star Ansel Elgort taking the challenge himself :)
