Ice Bucket Challenge: Northern Ireland people take plunge
The Ice Bucket Challenge is the latest internet craze, involving people pouring cold water over themselves and posting their videos online.
Well-known names from Cristiano Ronaldo and Lady Gaga to Bill Gates and Mark Zuckerberg have taken the plunge to raise money and awareness of the neurodegenerative disease, motor neurone disease.
"The challenge is that someone nominates you to dump a bucket of icy water over your head - you nominate other people and they have to comply within 24 hours or donate to charity," said Alana Hughes, who is a volunteer with the Northern Ireland branch of the Motor Neurone Disease Association.
"A lot of people are doing both because it's such a good cause."
She took the challenge live on BBC Radio Ulster along with Mark Currie, who was raising money for Macmillan Cancer Support.
While Ronaldo did his challenge in blazing sunshine, the chilly morning air in Belfast provided an extra frisson.
"The pasty white really adds to it," he said.
However, for one Northern Ireland couple, a bucket was not enough.
Rachel and Nigel Wasson had a digger full of water dumped over their heads.
