Fluid dynamics.

As the urine travels down your urethra it is under almost equal pressure from all sides. As the liquid escapes it loses contact with the vessel.

Through a process called adhesion the water in your product will experience a drag effect as the contact with the waste channel is extinguished. This drag is greatest in areas that contain the most perturbation.

The shape of the orifice that produces the stream produces the vast majority of the perturbative influence.

In this case the opening is a slit which produces semi-toroidal flows in the medium at the polar vertices.

Combine these forces (The sudden loss of pressure, the semi-toroidal flows, and adhesion) and the net effect is a torsion force on the stream.

The torsion force impels the fluid to twist and cohesion (water molecules are kind of like tiny magnets and really want to stick together) keeps the stream together.

There you have it. Why your urine spirals instead of just flowing out like a garden hose.

The spongy urethra runs along the length of the penis on its ventral (underneath) surface… This produces a spiral stream of urine and has the effect of cleaning the external urethral meatus. The lack of an equivalent mechanism in the female urethra partly explains why urinary tract infections occur so much more frequently in females.

Isn’t it interesting in how “officer discretion” disappears in instances like these?

On a large scale I have no idea but it does for me when I’m driving.

A crosswalk at an intersection, especially an unmetered one, serves as a warning that there’s enough regular pedestrian traffic or a risk that dictated it was needed.

Helps me, personally, to be extra aware for crossers.

In the 45-second video posted later that day, one girl enters the classroom holding a cellphone. “Put your hands up,” she says, while a classmate flickers the lights on and off. As the camera pans across the classroom, several girls dramatically fall back on a desk or the floor and lie motionless, pretending they were killed.

When another student enters and surveys the bodies on the ground in poorly feigned shock, few manage to suppress their giggles. Throughout the video, which ProPublica obtained, a line of text reads: “To be continued……”

Talk about an overreaction.

When I was a kid in the 90s I used to run around our neighborhood with other kids playing “War”. I had a realistic looking cap gun western revolver made out of pot metal, much like this one.

We never had police called on us or even got stopped by them on the rare occasion they were cruising through.

All feelings are valid. The issues come from how some express or act on those feeling.

Many of us are in the habit of mentally calculating it wherever we live though.

For example, my state sales tax is 6.88%, my county has a .25% tax on top of that, and then there’s a metro area tax of 1% on top of that, my city does not impose a separate tax of their own, so total sales tax in my city is 8.13%.

When shopping we’ll do the mental math (roughly) and factor that in so it might say $39.99 + tax but I know that it’ll be a little under $44 with tax.

It’s inconvenient but, like most things, we get used to it and adapt. Also, while tax varies a lot by state, most of us don’t venture too far out of our home area so tax is roughly the same all the places we regularly go.

It would be nice to have the price listed as the price you pay but it doesn’t work as well with our current system.

I must be ugly as sin. My wife and I have been married almost five years and I have yet to be in a situation where a woman is pursuing me and I can shout, “I don’t know you! You’re not my wife!” and run away.

It’s probably rented out for events like air shows, maybe film and tv use too.

I saw this same story from another source in a different post (https://archive.is/sZYDO).

There’s one specific paragraph in that article that is not covered in this one:

New York City has begun a crackdown on e-bikes and scooters riders. It follows actions by city officials from Paris to Honolulu to Hoboken, N.J., who are responding to residents angry about zippy vehicles with silent electric motors zooming down sidewalks and streets, often startling people, and occasionally hitting pedestrians.

That’d quickly become a game of whac-a-mole.
