Science in Seconds - The Straight Flush

0 (0 Likes / 0 Dislikes)
Science in Seconds Know Everything RUMOURS - The Straight Flush Torah Kachur: If science can be learned from the Simpsons, toilets flush counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. This is something called the Coriolis Effect, where the Earth's rotational force influences movement of matter. Thanks, Bart. So, the next obvious step, take a toilet to the equator and search for the straight flush. Well, Bart, eat my shorts. The straight flush doesn't exist, mostly because toilet jets all point in the counterclockwise direction. But the logic of the straight flush is correct. The Coriolis Effect is the appearance of a force because of the rotation of the Earth. Take one of those carousel thingies on tables in Chinese restaurants. If you put a rolling ball on it and spin, it will roll straight across the surface, despite the turning of the table. Now, imagine yourself spinning with the carousel and following the path of the ball. It will appear to curl! This is the Coriolis Effect. Toilets don't have enough water in them to be influenced by the rotational force, and they aren't a perfect system, so small asymmetries can affect the spin. At least, that is what all the science says. But the Coriolis Effect does influence water rotation during draining. So, in theory, the straight flush is possible - just not in a tiny toilet. But I know you don't believe me, so the next time you're at the equator, give it a go and flush away. Courtesy of Science in Seconds – All rights reserved Only for educational/non-profit purposes.
