Duck Quacks Don't Echo
Magnum Media for Sky 1, 7 February 2014 to present
Three celebrity guests bring an incredible fact with them, such as 'It is possible to start a fire by rapidly rubbing together two cool Ranch Doritos.' or 'You can make diamonds from peanut butter.' But whose fact is the best? All the celebs believe that their fact is absolutely true and they'll argue passionately for why it should win.

The programme was made in a one-hour version suitable for showing after the watershed, and a 30-minute edition that could go out anywhere in the schedules.
Magnum created Duck Quacks Don't Echo as an international format. It was quickly sold to the National Geographic channel in the USA, and began airing there a couple of weeks before appearing in the UK.
