You may have heard recently about the social media phenomenon known as the “Ice Bucket Challenge." This morning on Fox and Friends, it was Elisabeth's turn, as she shared the video of herself taking an ice cold dousing.

The challenge is to dump a bucket of ice cold water on your head in the name of ALS awareness, then post the video on social media and nominate friends to do the same.

Those who refuse the challenge are asked to make a donation to an ALS charity.

Elisabeth nominated her old Boston College roommate after being nominated by her sister-in-law, Sarah Hasselbeck.

"I just threw the ice over my head. Dealing with ALS and fighting through that is the real battle," she said this morning.

Watch it all above.
