List some BAD chemistry YouTube videos

 Pages:  1    3

DrMario - 24-11-2014 at 11:52

Post here some YouTube videos that are bad because either one or more of the categories apply:

- experimenter came to wrong conclusion (the wronger, the "better")
- experimenter used poor safety measures (the poorer the "better")
- video is not informative (the least informative, the "better")
- overall terrible presentation (the worse, the "better")
- "Lost Opportunity" category: the experiment used a great deal of chemicals which cost a fair amount of money, or showed an actually interesting reaction, but the experimenter was babbling around without talking about the most interesting aspect of the reaction, or he/she was not saying a word. This kind of ties in with "overall terrible presentation", but you may also consider it a separate category. It is loosely related to "video is not informative". But in my mind it is about a video that could have been an EPIC WIN but instead is an epic fail.

Some videos may feature only one category, but could"excel" in it so much as to be worthy of being posted here. Some videos may check multiple checkboxes. Some may check ALL of them.

There could be other categories of badness (or "goodness"), so please propose them and I will add them to the list, unless they're redundant.

Here's one, to start the ball rolling:

https://www.youtube.com/watch?v=uB7gzJnfP4Q

Issues:

- absolutely HORRIBLE safety measures, relative to the super-dangerous and very abundant mercury vapor! This is by far the main problem, here.
- really not very informative or interesting: we all know mercury is a good heat conductor - DUH!

Texium - 24-11-2014 at 12:23

Also, lost opportunity, because he just ruined FIVE POUNDS of mercury with little bits of fried egg! Imagine all of the better things he could have done with it.

Well, he did plenty of other (some equally shitty) experiments with mercury, that didn't need any particular purity. I think he could purify the mercury easily enough if he filtered it. The trace sulfur from the egg would not be possible to remove, though.

This is cringe-worthy on so many levels. I particularly like the way he makes his "acetic acid" and the optional use of scissors.
The reaction is not entirely bad. But someone teach this boy some stoichiometry. I estimate a kg of aluminium foil per teaspoon of product.

And if nothing else gets you, the music certainly will.

He always wears a gas mask (the type that protects you from Mercury). Well, he says he does. So you have no point on your first statement. Horrible safety measures? Meh, Horrible point you have.

Second, why isn't boiling eggs in Mercury interesting? It's more interesting than NOTHING. And it's always enjoyable to get to see Mercury doing its thing.

Why are the other videos shity? Don't you mean cool? If not, please do point out which videos are shity so I can show you why they aren't.

Hahah... and "This is where the scissors are optional"
also: "Now cobalt chloride doesnt know what color it should be"
and many other gems.

This video shows that maybe I need a new category: Stupid.
Or.. "Troll"? Is this a troll video?

Wow, are you that guy? You're very biased in his favor.

First of all: the mask may protect his lungs from mercury vapor, but his body certainly not. And in that situation in the video, the vapors were copious. His hair and skin have absorbed enormous quantities of mercury, which will affect his cognitive abilities almost immediately. And permanently.

Second: yes, I do think seeing an egg cooked in mercury is uninteresting and irrelevant. I don't care that you disagree.

Note that I didn't say the video is "shity"; I said it's shitty. I pride myself on moderately good spelling. Other shitty videos with mercury: mercury in corn syrup. Yeah, that's a waste of mercury. Yes, we kind of anticipated that mercury would sink below the less dense corn syrup.

Submerging a golf ball under mercury - lame.

And a host of other videos that, while not entirely shitty, are a waste of the discerning viewer's time.

I had the impression that in both videos the "actors" had little clue about what they were doing. In the second one the guy somehow reminded me of the Swedish Chef :D (Muppet Show reference).

Very short but following things:
-- Non-informative video of a coin in HNO3
-- No gloves whatsoever and I suspect that there is no fume hood
-- THE COPPER NITRATES + NITRIC ACID CONTENTS ARE JUST POURED DOWN THE SINK WHAT?

Haha [whining] "I didn't think that anything was gonna happen!" [/whining]
and "Well, somethin oxidized to somethin."

Also, about that cobalt video, I wouldn't say it was stupid, just inexperienced and cringeworthy as far as his procedures were. I know I went through a time when I did stuff like that all the time, I just had the sense to not make YouTube videos showcasing it. :) (and he really needs to find a spellchecker)

HgDinis25 - 24-11-2014 at 13:04

Wow, congrats you got me on the "shity" spelling. And no, I'm not that guy.

About your skin absorption non-sense:
"ROUTES OF EXPOSURE: Elemental mercury is toxic primarily through inhalation of mercury vapors. It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact. Ingestion is not an important route of acute exposure as almost no elemental mercury is absorbed through the gastrointestinal tract. "
http://www.cdc.gov/niosh/ershdb/EmergencyResponseCard_297500...

"Some mercury vapor is absorbed dermally, but uptake by this route is only about 1% of that by inhalation."
http://en.wikipedia.org/wiki/Mercury_poisoning

It will immediatlely affect his cognitive abbilities? Please, do tell me how it happens knowing there's no absorption through the lungs. If we watched the same video he doesn't put his hands above the mercury trying to get every inch of is skin covered by the vapour. And how does his hair absorb Mercury vapour? Thats kind of new to me...

Second: You said it all. About it beeing uninteresting or not is a matter of subjective opinion and thinking, thus not a good argumento when trying to prove a video is BAD.

About the other videos: again, just subjective opinion. I thought this was going to be about :
"- experimenter came to wrong conclusion (the wronger, the "better")
- experimenter used poor safety measures (the poorer the "better")
- video is not informative (the least informative, the "better")
- overall terrible presentation (the worse, the "better")
- "Lost Opportunity" category: the experiment used a great deal of chemicals which cost a fair amount of money, or showed an actually interesting reaction, but the experimenter was babbling around without talking about the most interesting aspect of the reaction, or he/she was not saying a word. This kind of ties in with "overall terrible presentation", but you may also consider it a separate category. It is loosely related to "video is not informative". But in my mind it is about a video that could have been an EPIC WIN but instead is an epic fail."

Where do you put the videos you mentioned? Not informative? Seriously? Even Mercury droplets rolling in a Petri dish is very interesting.

By the way, please do point out my wrong spelling. At the very least, I learn something...

Pretty bad in some aspects, but not so much for the environment. Copper nitrate isn't particularly toxic. Copper salts in generally aren't. As for nitric acid down the drain: not ideal, but then again, some companies sell concentrated sulfuric acid as drain cleaner, so there's that. :(

I'd be more curious to know what happens to the mercury that the dude in my first post uses.


Morgan - 24-11-2014 at 13:33

I remember in junior high the teacher had a somewhat larger than normal test tube partially filled with mercury. The test tube was sealed at the top and when heated there were these pink or bluish crystals I can't recall but they danced upon the surface of the mercury when heated. But there wasn't any visible boiling of the mercury. Kind of a neat demonstration.

j_sum1 - 24-11-2014 at 13:36

Thermite indoors was never a great idea
This could have been a whole lot worse.

Not just what HE could've done with it, think of what I could've done with it... what a waste...


In regards to videos, I ran into one with comments stating that a NaOH solution would dissolve the glass container that held it. Others stated that it wouldn't dissolve it, but would melt it from the heat released by it's dissolving in water. Boy, I called a lot of people youtube chemistry script kiddies and quiche eaters there...

subsecret - 24-11-2014 at 18:56

My videos aren't particularly good, but that's because I believe that captions for these videos would be excessive, and that I have a speech impediment, so I'd rather not lose face. But I figured it was my turn to help spread the awareness of home chemistry, however it's done.

iPhone 5 Dissolves in a Sodium Hydroxide Test

Let's see:
-Boiling sodium hydroxide WITHOUT a lid or any other means to eliminate the aerosolized hydroxide (many pots come with a glass lid you know)
-Adding water AFTER he heated the pot with NaOH, great way to aerosolize even more hydroxide
-He mentions that he used a gas mask (I see it in the phone reflection), but no hand protection anywhere.

Oh, and the best part: "It's a chemical, not an acid". :D

Texium - 6-12-2014 at 09:33

Mabus, I think you hit the terrible video jackpot with that one. Can't get much worse than that. I disliked it with every YouTube account I have access to.
Also, I wonder how long it took him to neutralize that much NaOH with vinegar? It must have taken a lot more than what he showed.

Mabus - 6-12-2014 at 09:44

You should see his mercury, liquid nitrogen and artillery shell fireworks test videos. They're just as bad.

The video of the Samsung Galaxy S 5 in mercury - it hurt my brain.

Besides, you just KNOW that a person so cavalier with expensive gadgets and such large amounts of mercury, is just going to dump it all somewhere in the forest.

Etaoin Shrdlu - 7-12-2014 at 11:43

I'm impressed with the number of people here who think it's a bad thing to try something out to see what happens. Compressing TATP in aluminum foil with your hands? Stupid. Because you're going to die. Leaving a phone to sit in a tub of mercury overnight? Come on. Why the hell not?

500g TATP C1 (dangerous??)
https://www.youtube.com/watch?v=3Z9wG9XbW2k

however the one who created the video did test this composition's physical stability, which were very unexpected, he couldnt detonate it with a hammer and took more than 2 grammes of TATP to detonate
but still its not one of the most chemically stable compounds, anyways

more edit: this gem: he performs runoff even before the .. cellulose is in the acids

Why on Earth would he dump the mercury in the forest when it fits into a pint container and he clearly enjoys owning it?

DrMario - 13-12-2014 at 04:55

He's got no qualms destroying expensive gadgets - he'll just discard the mercury just as easily.

Etaoin Shrdlu - 13-12-2014 at 14:35

He destroyed the (sure, we'll say "expensive") gadget for an experiment, out of curiosity. What exactly is he going to gain from dumping mercury out in the woods?

j_sum1 - 13-12-2014 at 14:51

I'm curious about the back story. How is it that he has so many phones that he is (presumably) unable to offload onto friends or relatives or sell? I don't for a.moment believe he is buying all those phones himself.
He comes across as cavalier and unknowledgeable. Whether this equates to irresponsible disposal or not is another question. I wouldn't be surprised.

It would be nice to see some more shockingly bad chemistry in this thread. That TATtP in alfoil was unbelieveable

I'm surprised no one seems to have linked to this one yet (correct me if I'm wrong on that): extraction of uranium from a high count carbonaceous U ore by the pool side:

https://www.youtube.com/watch?v=BRdZouC7CRo

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...

Probably not. I would have been a lot more concerned about how it was just left to sit in the middle of the room on a piece of filter paper though.

Not worth the hours spent or the potential acid burns.

At first I thought "WTF, is he really trying to make HF in a pyrex glass test tube??!" but soon I realized that that's not even remotely the only issue with his experiment! Are you kidding me? Handling HF without any safety equipment?

This is how we handle HF: long-sleeved tyvek aprons, long heavy-duty gloves and full-face shield/mask. And a mandatory tub of calcium gluconate gel in the proximity, as well as a shower in the lab.

Because we take HF seriously.

This video shows behavior that is in many ways more dangerous than in the one posted by Argentum:

I must say, I thin this is the video with the most egregious safety in handling dangerous chemicals, and it PROBABLY resulted in some (even though minor) damage to the retinas and mucous tissues of the people present. This is my candidate for "worst of the worst".

70 % HF used with minimal safety precautions: pretty bad.

Interesting to see how vigorously it reacts with glass though: loads of presumed SiF4 coming off...

Yeah, I've not seen such vigorous reaction of glass with HF. But honestly, I've never been silly enough to put HF in a glass vessel.

Also, I've never had the opportunity to use such concentrated HF solution.

Keep it that way until you've been trained in using it and have the needed equipment and countermeasures in place in case of a mishap.

Now I don't mean to be a jerk, because he's experimenting. I just don't understand the point. He dangerously took apart an old car battery, then used the case. In the end decided not to really use the case. So instead of taking a shower in lead/sulfuric acid he could of built the same thing in a rubber-made container for like 2 dollars.

Somehow I've never seen this thread before. The idiocy here is fantastic. It's just funny because people get worried about my technique when it comes to small things. IE: handling relatively small volumes strong acids without a lab-coat? c'mon... Here we have people making HF in glass test-tubes without gloves, cooking iphone's in sodium hydroxide, splish-splashing in 25year old lead acid battery electrolyte, drying radioactive peroxides with space heaters(after vacuum filtering them without support ~10cm away from the family pool). Love the guy 5cm away from the test-tube being digested and emitting copious amounts of steam + HF wearing kitchen gloves. There aren't even public service announcements dumb enough to mitigate such behaviours.

How about barefoot HCN synthesis? https://www.youtube.com/watch?v=zluomv5gHdU

I do go through training for using HF (we use 49% concentration), which includes a hands-on and a written exam. I think that's more than 99% of the grad students do in the US before they get their hands on such chemicals. Just thought I'd point that out.

I, for one, didn't finish watching it. The last thing I saw was his mom helping him to disassemble the battery case (here a rollseyes emoticon would suit perfectly).

Thank you very much for writing a nice summary of the thread so far :D and also thank you for that link - that video is all kinds of shitty, but not enough info to know how dangerous the behavior was. But yeah, the overall shittyness makes it deserving of this thread.

Excellent. Despite its potential lethality it's an extremely useful chemical.

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...


[Edited on 14-12-2014 by blogfast25]

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.

Are you insane? :o 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.

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.
