Ice Bucket Challenge

The format is straightforward: a nominee films themselves accepting the challenge, empties a bucket of ice water over their head, and calls out three more people who then have 24 hours to do the same or donate to an ALS charity1. Stakes varied by group. Some circles asked for a $10 donation on top of completing the pour and $100 for opting out10. Critics called the whole thing slacktivism at its worst, since a wet stunt could look like activism without the participant giving anything meaningful8.

The visual was the point. A person standing in a driveway or backyard, filming vertically on a phone, gasping as freezing water hit them, made for perfect Facebook and Instagram content in 20141. Nominations added built-in social pressure since being called out publicly meant either performing on camera or explaining why not. Celebrities, athletes, politicians, and executives cycled through the format for weeks, from Bill Gates to Barack Obama to Oprah Winfrey10.

The typical version goes like this: get nominated on social media, then within 24 hours film a short clip announcing who called you out, dump a full bucket of ice water over your head, and name one to three people who face the same 24-hour deadline. Opting out means donating $100 to an ALS charity10. Some groups ran a variant asking for a $10 donation for completing the challenge and $100 only if you skipped it, though enforcement was always on the honor system10.
