Everyone from former United States President George W. Bush to celebrities such as Bill Gates and Oprah has dumped buckets of ice water over their heads in recent days.

If you spend any amount of time on social media, you have seen videos of your friends doing the same.

But in case you haven’t heard, a viral fundraising campaign — the Ice Bucket Challenge — is, ironically, the hottest thing on social media right now. People from all over the country have taken the challenge to dump buckets of ice water over themselves to raise money and awareness for ALS, or Lou Gehrig’s Disease, a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.

It’s a simple concept: Donate $100 to the ALS Association or film yourself dumping a bucket of ice cold water over your head. Then, publically challenge others to do the same.

Some have asked, “How is ice water going to cure ALS?”

Well, it’s not going to cure anything. But it has brought the disease into the forefront again and thankfully, most of those participating in the challenge are also donating money that will go towards finding a cure.

In fact, according to the ALS Association, almost $16 million was raised between July 29 and Aug. 18.

The Ice Bucket Challenge may seem strange to some, but this viral sensation has the potential to do a lot of good for many worthy charities all over the world. If you have a charity close to your heart, get your buckets filled and invite others to do the same.

It’s all for a good cause.
