Hundreds of young men took to the streets of North Belfast in a bid to clean the area in a fundraising effort to buy a community defibrillator.
The pupils from the Boys Model High School, on the Ballysillan Road, swapped note pads for little pickers and collected bin bags of rubbish from the streets.
Belfast Live attended one of their cleanups on Thursday, where scores of class mates engaged in some healthy competition in the Ballysillan area - the school is divided up into a house system, and whichever house collects the most rubbish, wins a prize.
