Hi John:
In my youth I made black powder from drug store ingredients and later
bought it in metal cans.
I think the relative cost of labor has changed greatly over time. For
example it used to be that you could buy a new U.S. automotive head lamp
(reflector type) for under a dollar and have it installed and aligned
for not much more money. But today the lamp is still under a dollar but
the installation and alignment is a small fortune. By contrast a Honda
lamp bulb (reflector is part of car) costs about $10 and you can install
it in less than a minute, no alignment required. The cost of the
installed lamp is much lower for the Honda.
In order to lower the selling price it's common practice for a
manufacturer to buy custom ICs which reduce board area. But, being
custom, there are no replacement parts so no repair. When you can buy a
new DVD player for about $40 it's a throwaway product, not economical to
repair even if you could get parts.
The Toyota Prius under charges and under discharges it's battery (66%
SOC & 33% SOC) to prolong it's life. The battery lasts three times
longer, the customer pays three times as much for the battery. (I
wonder if there's a hack to change the SOC limits?) Makes the warranty
more impressive.
Have Fun,
Brooke Clarke

In the '50s, WW II was not ancient history. We met people who had used
weapons, explosives, and other things in war and knew the risks. The same
is true, but in a much more limited way, after 'Nam.
However, starting in the '60s, society regarded science as evil and it
became political. More recently, science has been warped to support
political agendas.
In a related way, cars, radios, TVs, and computers have "matured" to the
point that even technically competant individuals can no longer modify or
even repair them. (They still don't know if the Toyota failures are
hardware, software, or a mix.)
We are all becomng hostages to the priesthood of so called "experts" in
big government and the big corporations, and we really have little idea
what is fact and what is politically motivated disinformation.
FWIW,

As a kid in the later 50's we made all sorts of pipe bombs and other
interesting things. Potassium Nitrate was available as Saltpeter in
drugstores as was other stuff, like Glycerin and Potassium Permologate.
Amazing, we had a fun time, and, no one was ever hurt. Today we would be
deemed as "terrorists". We could even go into a gun store and buy shotgun
shells to take apart just for the powder. Regards - Mike

Yeah. I want fries with my fries. :=))
As a kid, doing real chemistry and physic was what made school fun. We had
real labs too! With real glassware and real chemicals.
I'd have been utterly bored stiff with what they are teaching now.

No argument.
BTW, you want fries with that?
