Pressures Produced When Penguins Poo -- Calculations on Avian Defecation
"They get up, move to the edge of the nest, turn around, bend over... and shoot"

Ever wondered how far a penguin can fire waste from its anus? Wonder no more. Victor Breno Meyer-Rochow of International University, Bremen, and Jozsef Gal of Lorand Eotvos University, Hungary, used the basic principles of physics to calculate the pressure that builds up inside a penguin. Dr. Meyer-Rochow explained that the research began in 1993, when he led the first, and so far only, Jamaican expedition to the Antarctic. Later, while showing students pictures of faeces-lined penguin nests, he was asked how the elaborate displays were created. "They get up, move to the edge of the nest, turn around, bend over - and shoot," he said. That's when he got the idea to calculate the pressure produced by penguin poo.
