What started with a simple challenge by CUES and the $582 million CitizensFirst Credit Union has spurred others across the credit union industry to get soaked for a good cause.

Credit unions and their vendors have joined the national ALS Ice Bucket Challenge, pouring a bucket of ice water over their heads to raise money for charities that support victims of amyotrophic lateral sclerosis, also known as Lou Gehrig's Disease. ALS attacks nerve cells, ultimately leading to paralysis. Countless celebrities and everyday people have participated in the trend.

Here is how the Ice Bucket Challenge works. Participants post videos of themselves getting soaked on Facebook, Instagram, Google+ or Twitter and nominate three others to do the same within 24 hours and make a donation of $10 per person, or $100 total. Those challenged can opt out of taking the icy bath and simply make a donation. Funds raised not only help further research for a cure but also go toward providing care for those living with the disease.

According to the ALS Association, the viral campaign has not only helped raise awareness but more than tripled donations raised during the same time period last year.

Here's a look at how those across the credit union industry have answered the call:
