Oh, I just meant :HITLER & FLUORIDE added High Dose to Water at Concentration Camps Keep People LIKE WALKING DEAD was a good
title.
Saponification videos usually have really bad chemistry tidbits in them.

I actually liked the video, because the poster clearly posted it as satire, although the person who's talking thinks he's right.

Testing explosives from The Anarchist Cookbook
This is one of the worst videos I've seen. Terrible safety measures, scientifically illiterate idoits creating lame "explosives" - non of which are
actual explosives.
Using the wrong equipment, and worst of all, they tested the shittiest "explosives" in the damn book!

Watch him dry his impure U compound with a blower heater! (in the comments he claims it was fine because... the garage doors were closed! Ooo-kaay)
It's an impressive case of a guy who on the one hand seems to understand the chemistry well, yet on the other hand is clueless with regards to
radiation hazards...

Help me a little here. Just how radioactive is the.materual he is working with? He has concentrated several kg of ore down to a couple of grams. But
how potent are those rocks to begin with? What does 4000 cpm mean in terms of hazard value?
You can tell I have zero actual experience of radioactive substances beyond a smoke alarm.
I will admit that the whole process freaked me out a but. If it was a mercury or cadmium ore and he applied the same lack of care I would be very
concerned. How much more concerning is this U refinement with both chemical and radiation risks?

Actually it is rather bad. Missed opportunity to give some interesting information/education, terrible safety (with good chance of getting burning
alkaline metal on skin X 2, glass shards into eyes, or burning down a house X 2).
It was still funny, and at times hilarious.

The following video is, in my humble view, terrible because it shows a teacher who is handling 5 molar HCl without any protection - even his labcoat
is not buttoned up (not like that would make a terrible difference). Furthermore, he involves a child to help him, likewise with no protection. I take
umbrage at the scandalous behavior of this educator.

This one isn't exactly terrible, but the way the dude whacks the table with the bottle, and his many unsuccessful attempts at re-igniting a blown-out
wick make it funny. And a bit bad.

Are you insane?  The concentration of that HCl is less than 20% (5M). Many labs
actualy recomend not to use gloves when handling HCl in such concentrations so one does not lose sensibility in the hands. If some of it gets into
your hands, just wash it off.
https://www.youtube.com/watch?v=daQtnshQD2U
Here The Home Scientist explains what I've just written and makes a pratical example (he puts some HCl in his hand).
And this goes for the lab coat. Non required. Perhaps, some googles, to avoid splashes from the exothermic reaction. What this teacher did was show
some very interesting chemistry to a bunch of students without making it appear like he is messing with the devil, like many do.
Really what's scandalous here is you describing the teacher's behaviour as scandalous.

I agree, 5 molar HCl couldn't hurt anything unless you dont have access to water. Treating all chemicals like they're super dangerous leads to more
chemophobia.

This is an interesting one. It's not action packed it's really just a video of some guy babbling about his titanium dioxide speculations. Kinda funny.
Nothing against the guy, but I mean, mind control? hahaha.

This is amazing. I cannot believe how convoluted and wrong absolutely everything is in this video. It's great because he's making shit up that he
could of easily fact-checked all for the agenda of getting more people to drink their own piss. "Drinking urine is like fuel injector cleaner" That's
some life changing shit right there lol.

As so often with those goofballs, the comment section is the real fun, for instance:

What Mr. Webber is explaining is, quite possibly, the crime of century. To not have an inexpensive water distiller in EVERY home is criminal offense,
war against the general health of its citizens and for what, irresponsible corporate profit with intentional decimation of our precious resources?!

His website has a picture of him. He totally looks like a punk.
But the "Will this come off?" In regards to the lithium video was totally the best. Probably because it reminded me of (and possibly was) an old
friend of mine from elementary school.

You have quite the nerve calling someone "insane", while completely ignoring that 5M HCl is a 18% solution, which is still very corrosive. It is a
concentration that can cause burns with many kinds of skin, especially longer exposure. And if you get this concentrated HCl solution on your clothes,
that's exactly what you end up having - an extended (as in time but also area) exposure.
And so I am "insane" for advocating a cautions approach, and because I think children who don't know any better at this point should learn to show
respect for corrosive liquids? Sure, HCl is tame compared to other acids and concentrated alkaline solutions, but it's still dangerous enough that it
can cause burns. Learning to be mindful and disciplined with handling dangerous chemicals, even if they are not that dangerous, pays
dividends in the long run - you learn to cross your T's and dot your I's when you handle the more dangerous stuff.
I am baffled by your statement that "the lab coat is not needed" - as little protection as it may give, it's still better than getting 18% or so
concentrated HCl on your own clothes. I am even more baffled because you felt indignant and haughty enough to call me "insane". When someone has such
strong opinions, I do not have any hope to actually have a reasonable scientific conversation (a conversation where one of the parties can actually
see the argument and accept it) but I didn't want to simply report your post - I wanted to make sure this is written down for those who might read
this thread later. I didn't want to leave your self-confident and very wrong post unchallenged, a someone who knows no better might be convinced by
the tone of it.
For the record, at my (main, I have two affiliations) institution we handle HCl solutions with the same safety equipment as we do the other corrosive
substances, which includes full face shield, long thick gloves and tyvek-like apron. This policy has saved us a lot of problems in the last 10 years
since the institution was opened. Thousands of people have worked there during this decade, and I guess the lab engineers responsible for safety know
their business rather well and have a good track record to support them.
Now I know for a fact that safety in US research institutions is lax compared to ours (and other North European institutions in general), so there's
also a cultural thing going on here, but you should really try to step back and look at the big picture more objectively before you call someone who
advocated better safety as "insane".
Oh, I'm not convincing you at all, I know that. But this had to be written.
