This year, the Ice Bucket Challenge, which involves daring friends via social media to dump ice water on their heads or donate money to ALS research, has returned, though not quite on the same scale. So far in 2015, through Tuesday, the ALS Association has received more than $500,000 from the challenge specifically, according to spokeswoman Carrie Munk.
"I don't think anyone expected fundraising to be near where it was last year," Munk said. "But people are taking the challenge again this August and embracing the idea that we have to do it every August until there's a cure."
Among famous people taking the challenge this year: Microsoft CEO Satya Nadella, Justin Bieber, Renee Zellweger (who made hers drought-conscious) and Massachusetts Gov. Charlie Baker. In perhaps the ultimate mark of legitimacy, Donald Trump pooh-poohed it, though he took the challenge last year.
