Cool
I never got this teacher.
No gloves?¿★If this accidentally get in your tissue,you will have a bad day★
drinK your bottle of Mercury out !!!! AND THAN I give you like !
Liquid metallic mercury is poorly absorbed by ingestion and skin contact. It is only hazardous due to its potential to release mercury vapor.
please wear gloves!
wtf, you think it's safe to touch led, but not mercury x face palm x but hey good videos!
brace yourselves….mercury and no gloves.
Dear lord man, use protective clothing!
Jeez, you got a brain for a reason. The human race would appreciate if you use it.
Murcury is seriously toxic why dont u wear gloves
you should lay some plastic cover under it, just in case it spills, cause it would be night ware to clean up mercury beads from the carpet
where can you get it?
can we convert hg to au use radio active reaction . h2so4 ect ….
How come lead is floating? lead is 82 while mercury is 80, was this heavy isotope of mercury or lite isotope of lead? or is it because of surface tension?
What is the safest way to dispose of mercury?
@mkgecko the compounds are much more toxic than elemental mercury but that doesnt mean elemental mercury isnt very toxic. Im a chemist and we have done numerous LD 50 tests and mercury is lethally toxic to a part per billion level.
He is really good teacher~
My face when this is my physics teacher.
Mr.HarOOO: What?! Did I touch that?! LOL
>.>
@sgteltorcho Of course it is, but our country is like this, it is very common here.
@rhinogek I know this is an old comment, but that's not true. :/ I hate it when people like you stereotype the US. I'm not American or anything, but what you're saying is a dead opinion. Not a fact…
how did you come to obtain the mercury? Are you a professor?
Mercury is problematic. Even when you poor it, you get tiny drops all over the beaker and outside. It took me a long time to collect all the tiny drops. I did it outside just for the reason you get droplets.
@RSClassicAngel No one is forcing you to watch this. I made it for educational purposes. You could also learn some manners (and maybe humour).
Surely, elemental Hg should always be handled wearing gloves. Anything else is complete and utter stupidity. I you have a sratch on your finger whilst handling it, it might get into the bloodstream.
Don't be a fool and run a risk that high, when the precations needed are so minute and easy to overcome:)
regards
Lol so much hype about handling elemental mercury, its the salts that are really dangerous.
@mkgecko Yep, the average north american is pretty dumb. I'm up here researching and learning while others downstairs are watching garbage TV
Alright… Time for the taste test…
@DaveArgon
Man, I could not agree with you more. Reading youtube comments actually scares me. Do they actually reflect the intelligence of the average native english speaker? Or, is it that only the stupid people dare comment while the more intelligent refrain? If I had kids I would be scared. I can imagine that soon most people will be, if not already so, incapable of reading classic literature.
