Would YOU fry a radioactive powder that way?

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.

And what about these pool side filtrations? I was kind of waiting for his set up to tumble into the family's swimming pool!

That part made me cringe pretty hard, too. I just know I would have knocked that over.

At least he had gloves on I guess

Dont ask me, I only know enough to be dangerous

I hope you didn't actually watch that whole video LGA.

good tips ,i wish he was my chem teacher

He's right, you know?
Anyway, not a bad video, definitely not the topic of this thread

The mind boggles from start to finish.

He's sentimentally attached to a 21year old car battery and re-used the plastic??? I just don't get it.
Not worth the hours spent or the potential acid burns.

Making "Hydrofluoric acid". No comments.

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.

I was speechless by the 3 minute mark already. The events surrounding the battery acid splash were but one of the reasons for my bafflement.

This video shows behavior that is in many ways more dangerous than in the one posted by Argentum:
https://www.youtube.com/watch?v=Lf4vq2UU9hk

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

My point was the video was sooo boring, I can't imagine a better way to waist your time.
The video probably wasn't that bad, but unless you're in the same position as him, why watch it?

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

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.
