Most babies spit up after each feeding or while burping. It is common for the baby to spit up a mouthful of milk when he burps.

And using this baseline for a penguin on the ground, the scientists extend the 2003 paper into a new analysis of what happens when a penguin on higher ground, like from the edge of a cliff, releases waste from a greater height: “In the presence of the viscous resistance, the grounding time and the flying distance of faeces can be expressed in terms of Lambert W function. That means for a human to have the backdoor thrust of a penguin, they’d need to be able to propel waste matter almost 6 feet away. Therefore, one can immediately understand that penguin’s rectal pressure is relatively much compared to that of a human.” Since a typical height of a Humboldt penguin is given by 0.4 m, this distance corresponds to the situation that if a human being whose height is 1.7 m tries to evacuate his/her bowels, the object could fly to 1.7 m away. Hiroyuki Tajima and Fumiya Fujisawa, from Japan’s Kochi University and the Katsurahama Aquarium, collaborated on “Projectile Trajectory of Penguin’s Faeces and Rectal Pressure Revisited.” They explain their findings: “The flying distance of penguin’s faeces reaches about 0.4 m even on the ground. The new research is on arXiv, but it hasn’t been reviewed or accepted for publication yet, presumably because all other scientists are cowards. In a new study, researchers revisit an Ignobel-winning 2003 paper about the physics of penguin feces. But scientists hope you have some room in your heart to think about a very different kind of fluid: penguin poo. In 2020, Americans have learned a lot about fluid dynamics, such as the way our breath droplets spray through the air when we're not wearing a protective mask. Penguins must expel waste a long way while protecting their young in the nest.A new paper calculates the propulsive pressure of penguin waste.
