What have former US president George W Bush, West Briton reporter Chris Matthews and a 102-year-old great grandfather from Chesterfield got in common?
The answer is simple - they have all undertaken the 'ice bucket challenge' in the name of charity.
Anyone with a Facebook account will have seen dozens of the videos already - with willing (in some cases) participants having a bucket of ice water poured over their heads.
In return for undertaking the challenge, the icy victim can then nominate three more people to step forward to face the bucket.
Everyone who takes part themn makes a donation to charity - with the vast majority of donations going to the Motor Neurone Disease Association in the UK.
Here we have compiled a collection of ice bucket challenges from across Cornwall - but we also want to know about yours.
