The Ice Bucket Challenge Explained

The Ice Bucket Challenge involved pouring ice water over a head during July and August 2014.

Nominated participants had 24 hours to comply or forfeit by making a charitable financial donation. Doing both was encouraged.

The original event raised over $115m worldwide in 2014 alone, with more than 2.4 million videos.

On August 1, 2015, a group of ALS organizations re-introduced the challenge to raise further funds. The ice had barely melted.

Araki launched a channel for the ice challenge.

By early October, the 2015 challenge had raised $500,000. Only 14% of donors from 2014 donated again.

President Barack Obama was challenged but declined, opting to contribute with a donation of $100. A hundred dollars buys a very dry shirt.

In 2016, a variant replaced ice cubes with tomato ketchup, spaghetti, pickles, beer, baby powder, coffee, sand.
