This absolutely works on shower heads and kitchen nozzles. The vinegar also works on that black crust that forms in the toilet outflow tract that looks like fecal stain but is just calcium and probably iron for the color and is resistant to the typical scrub brush. What you need to do is shut off the toilet water from the wall, then flush to remove most of the residual water in the bowl, then scoop out the rest with a plastic cup (so the vinegar won't get diluted) and then pour in half a jug of vinegar (it's cheap) and let it sit overnight, then scrub with the brush. Repeat as necessary. This may be TMI but it's the sort of information you don't learn in school and eventually need for adulting.
No no no. "800 percent" is not 800 times. 800 percent is 8 times, just as 100 percent is one times. Water is not 8 times as dense as air. A heavy gas might be 8 times as dense as air and sink to the floor of a room. Water is about 800 times as dense as air.
"Water has a density of 1000 kg/m^3. If you had a meter cubed of water it would weight about 1000 kg. Air that is near sea level has a density that averages 1.275 kg/m^3. If you have a balloon containing a meter cubed of sea level air, the air itself would weight only 1.275 kg. Therefore, to find how much more dense water is than air all we need to do is find a ratio of water to air. 1000 kg/m^3 divided by 1.275 kg/m^3 yields 784. Therefore, at sea level, air is 784 times less dense than water. Expressed in another way, a volume of air at sea level has 0.1275% of the density of the same volume of water. "
The Cosmo article quotes eBay ASKING prices, which are often different from actual selling prices by a log power or more. The Smurf Mini Ninendo Classic described as "selling for $541" is listed as having "sold" for $38.70 multiple times.
The linked article is concise, but for those interested in the topic it's way, way better to listen to Jad Abumrad's podcast, where he lets Dolly tell the story. The entire "Dolly Parton's America" series is superb, IMHO.
It's a mesmerizing presentation. Takes a while to appreciate that entities can move down in the rankings even while the absolute number of visits is rising because the scale is proportional.

I think they meant water is 800 times denser than air.
And blogworthy. Nice find, John.
