David Beckham has done it, Bill Gates took on the challenge and even former president George W Bush has had a go.
The Ice Bucket Challenge has taken social media by storm, with celebrities queuing up to tip a bucket of ice cold water over their heads in support of American charity the ALS Association.
The association supports sufferers of amyotrophic lateral sclerosis, a neurodegenerative disease, and funds research into finding a cure.
This week Mirfield-born star Sir Patrick Stewart posed his own Ice Bucket Challenge video - with a twist.

Instead of tipping the usual mix of icy cold water and ice cubes over his head, Sir Patrick calmly writes a cheque for the ALS Association, before pulling a full ice bucket towards him.
He then uses tongs to carefully place the ice cubes in a glass, pours himself a glass of whisky, and raises a glass to his audience before taking a satisfying sip.
The suave Star Trek star posted the video on his Twitter account.

As well as supporting the ALS Association, some have been using the Ice Bucket Challenge phenomenon to raise money for Macmillan Cancer Care.
Tragically, the co-founder of the chilly stunt, 27-year-old Corey Griffin, drowned in a diving accident earlier this month. He began raising money for the ALS Association after his friend Pete Frates was diagnosed with amyotrophic lateral sclerosis.
