TV presenter Adrian Chiles joined 500 others to help break the world record for the largest sub-aqua dinner party.
The Guinness Book of Records is set to confirm exactly how many guests sat down to the gourmet meal of smoked salmon, vegetables and toffee apple.
Wearing dinner jackets and ball gowns, diners indulged in their three-course meal at the outdoor swimming pool at The Park Club in Acton, west London.
The food - which was served to sittings of about 20 people every 20 minutes - was prepared in jelly to stop it from disintegrating in the water.
To eat, the diners had to remove their aqua lung mouth pieces, fork in the food and then replace the breathing equipment while pressing a button to purge away the water.
The event raised more than £200,000 ($400,000) for charities including Save the Children, The Shooting Star Hospice, Breakthrough Breast Cancer and The British Heart Foundation.
