Former President George W. Bush became the latest person to take the ice bucket challenge and he's challenging former President Bill Clinton to take it himself.
With the ice bucket challenge, it's process where a person posts a video of themselves dumping a bucket of ice cold water over their heads. At the end of the video the person calls on specific people to either take the challenge or donate to charity.
In the last several weeks the charity stunt has really taken off, raising millions for ALS.
A medical definition of ALS from the ALS association is below:
Amyotrophic lateral sclerosis (ALS), often referred to as "Lou Gehrig's Disease," is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.
So far, the ice bucket challenge has raised more than $30 million for the ALS Association.
