It's an act of kindness that's gone viral, requiring people to take a plunge into water.
The Mercer County varsity softball team is taking a break from the field to take a dip in a pool. That pool water is 51 degrees.
"It was freezing," said softball player, Jessica Brooks.
You might think they're crazy, but it's trending in Mercer County. They're calling it the polar plunge and once you've been challenged, its your turn to take a dive.
"Before they do the plunge, they say their name and who they're going to call out and what foundation they're donating to," Brooks explaining how it works.
Videos all over Facebook of teachers, neighbors, friends and family, no one is safe from taking the plunge.
"All of a sudden one day like it blew up and then it seems like the whole town of Aledo got called out," said Symone Silva, who jumped for charity.
As the sun started to go down, you could find more jumpers waiting to take a leap.
"I was completely insane for even thinking about jumping off a bridge. It's a long way down," said Silva.
For Tab Balmer it's his second go around.
"It takes your breath away," said Balmer.
Their advice for future jumpers is to be ready because you never know, your turn could be next.
"Good luck to those who still have to plunge," said Silva.
You don't have to plunge if you don't want to. The person who nominated you would choose a charity of their choice for you to donate money to.
