Many are dousing themselves with ice cold water and calling out others to do the same, as a way to raise awareness and help the fight against ALS.
It's simple: Grab a bucket of ice water, record it being dumped on your head, and challenge anyone you want to do the same. If they don't, they have to donate $100 to an ALS organization.
"It came out of nowhere. A baseball arena in the Boston area started the challenge," said Dr. Raymond Onders with University Hospitals.
"The Ice Bucket Challenge has been a great fundraiser for research this summer," said Onders.
According to the foundation, almost 6,000 people are diagnosed with ALS each year.
Onders' sister also died from the disease.
"ALS is a terrible disease. We don't know the cause. We need more research funding for that," he said.
"It's not just posting the videos," said Onders. "[It's about] bringing awareness to people that we need to work on this to help patients with ALS."
