Mythbusters is about methodology and entertainment.
it's mostly about the distance
If the pipe walls had "rifling" (an internal swirling pattern), the fluid would rotate on it's way down. Rotation inhibits momentum exchange between the center and edges because of the Coriolis effect: a parcel of fluid moving outward will find itself moving inward at half a rotation later.
It's not unreasonable to say nature figured this out long ago. Visually this even kinda checks out, I think. But I'm not gonna use any methodology to figure this out so really I'm just talking out of my... (haha. I'll let someone else finish that sentence.)
"The expansion of the auto industry nearly a century ago fueled a growth spurt that made Detroit the fourth largest city in the country. By 1950, the population peaked at almost 1.85 million as people moved to Detroit to work at the Big Three auto companies: Ford, General Motors and Chrysler. But it was at the height of this prosperity that the manufacturers began to restructure, and the risks of the city's reliance on a single industry became apparent, according to Thomas J. Sugrue's essay "Motor City: The Story of Detroit."First, there was decentralization. Strikes, inspired by union negotiations and a refusal by blacks and whites to work side by side, were halting progress, according to "Detroit, Race and Uneven Development," co-written by Joe T. Darden. Factories were built in the suburbs and in neighboring states so that if there was a protest in one factory, work could still continue elsewhere. But as the factories spread out, so too did the job opportunities.When the industry then experimented with automation, replacing assembly-line jobs with machinery, tens of thousands of jobs were lost. The industry shrank even more during the energy crisis in the 1970s and the economic recession in the 1980s. And foreign competition caused profits to plummet.As auto jobs moved elsewhere and the region aged, Detroit's labor costs -- retiree health care costs, especially -- increased substantially.Though other cities experienced their own booms and busts, Detroit suffered more because it didn't diversify, said Kevin Boyle, a Detroit historian who has written extensively about his native city. Places such as Chicago and Pittsburgh relied on other areas - like banking or education - beyond the industries that started their success.The auto industry "was like Silicon Valley in the 1980s," Mr. Boyle said. It was doing so well, he said, that Detroit officials didn't see a need to do anything differently. Tensions between the races have been high since the 1940s, when Southern blacks began moving to Detroit in search of work at automobile factories, said Mr. Boyle, the historian.As the migration of blacks who swept into Detroit became especially intense, middle-class whites began moving to the newly built suburbs. But violent 1967 riots turned this stream into a torrent."It's really hard to overstate how deep the fear was, on both sides of the color line," Mr. Boyle said.And after the riots, Detroit failed to bounce back, Mr. Boyle said. Businesses followed their customers. Thousands of houses were abandoned as the city's population plunged."In some cities like Chicago, Boston and maybe New York, people say to themselves, 'I want to be in this neighborhood where I grew up, where my grandparents live or where my synagogue is' -- that really roots people in place," he said. "Detroit didn't work that way."During the 1950s, the city lost 363,000 white residents while it gained 182,000 black residents. In 1950, the population was 16 percent black, and by the time of the 1967 riot it had grown to a third. Today, about 82 percent of the city's population is black."
It is a shocking thing in a non-Third World country for such a situation to be occurring and one cannot but feel a sadness for those suffering.
Aye but we are hardy folk here new southern man. undefined

It isn't the party; it's the people in charge. For instance, many of our best cities. Are highly democratic.
