Many of football's biggest stars have all taken part in the trending ice bucket challenge. Which video was your favorite?

With the rise of social media, it seems like every time one turns around there's a new trend that has quickly gone viral as everyone wants to get a piece of what's trending.

The latest fad, called the "Ice Bucket Challenge" initially seems like one of those silly things that attention-seeking teenagers do just to get a bit of fame on the internet. However, it's not--with many of the top football players getting in on the action not for likes on social media, but rather for a more noble cause: to raise funds for research, namely ALS and other health conditions.

Stars from Europe's biggest leagues, including La Liga duo Lionel Messi and Cristiano Ronaldo, Brazilian stars Thiago Silva, Kaka, and Neymar, Premier League icon  Steven Gerrard, World Cup winner Mesut Ozil, Milan's Mario Balotelli, and more have all decided to douse themselves with freezing water all in the name of charity.

Check out some of their videos below:
