I would have enjoyed watching the bell reach room temperature slowly. It would have been a melting mercury bell then. I wouldn't have expected it to ring - given that it is a property of tempering the metal not just of solidifying it. But interesting nonetheless.
semi-impossible... contradiction in terms, do we actually pay for guys to do this? pointless beyond belief, i dont understand how it is 'undooable' its just like casting an ice cube just smaller, colder and less brittle so in fact it would be easier to cast mercury than ice!
I admire this guy for doing undoable :) Thinking outside of the box, letting the little boy play a little in the middle of serious adult world... Everyone should follow his example instead of whining tha at lead ballon is impossible ;)
This is kind of interesting, but... why a bell of all things? I suppose why NOT a bell, but I'm interested to know if it was a random shape picked or if he chose it for a reason...
I love how disinterested the professor looks. hehe.
@SupremeCommander360 After living in a place where most people have a different accent, some people start to incorporate sounds they hear daily. Some never fully lose their original accent and develop a kind of hybrid, while some will keep their old one or just take on the new one altogether. I would think seeing as this man appears to be an American who has been living in London for some time that he's just sort of unconsciously picked up on some of the familiar sounds he hears every day.
wow, that dude is a nerd "very much like a tomb in egypt". The professor obviously did not care about this. Mercury is old news, its a nasty toxic element that is proven to make you go mad
profesor was not amused :P and neither was I. I mean, I've seen people make things with Mercury and liquid nitrogen by putting them in a mold. Oh Professor, why did they make you travel so far for nothing? :/
@RoMMeL1337ak47 You've obviously never googled it. I just read an article about liquid carbon forming nanotubes on a molecular level the title is "Liquid carbon plays role in nanotube formation"
@Slashpoint001 nope you know nothing about chemistry :/ iodine cannot be a liquid it is the only element and one of the only 2 substances (CO2 being the other one) that sublimates (goes straight from solid to gas with no liquid state).
@wideangle44 iodine and CO2 can both be liqiuds, why even some of the proffesors work is on liqiud CO2 and super critical fluids. It all depends on pressure, CO2 and iodine are never liquids at room tempreture however.
@wideangle44 Look, dont tell me I know nothing about chemistry thats a very crude statement considering that my comment was the first comment from me you have seen. And iodine can be a liquid, its just not a liquid for very long when its exposed to an increasing temperature.
of all things, why a bell? i like the idea of mercury being a solid functional object, and i would have asked the same thing as the professor wondering if it was to accomplish something. i would have liked to see something mechanical, or maybe if it could actually ring. i feel bad for the professor, he doesn't need this kind of time wasted. i'd much rather see experiments done with solidified mercury and elements it reacts with
It lacks the metallic lustre / may be in this video, how about its bonding, whether crysatalline, it seems amorphous.may become sonorous upon slow coolingin which case it may have metallic bond, and a thinner bell may do.
yeah this guys strange mercury obsession is probably exhasurbated by the vast amount of mercury toxicity he has suffered from. The professor looks like he was bored out of his mind and totally not interested about the Mercury Bell that DOESNT RING!
if ur reading this u cant go back there was a dad who got pissed couse he got layed off so he went home took a knife than went to his 13 year old daughter and slit her neck! if u r reading this and dont forward to 10 vids the 13 year old girl be sitting on the endge of the bed waitin for u when u wake up who ever takes care of u will find u in the tube full of blood with ur throat slit and than the 13 year old girl will come to who ever takes care of u so hurry dont be the that unlucky one! sry

Uh huh....what a complete waste of time and resources. What did he discover? I wouldn't even bother walking out of my front door to look at his bell...
I guess so. At least some of them. But since the professor said that you can find it as vapor in hot countries, I guess that it vaporizes way below boilingpoint.
Mercury is only poisonous when ingested. It's perfectly harmless to touch, as long as you don't swallow etc any. You may have heard the bell guy mention he saw a picture of someone sitting on mercury.
Yeah, but jacobssandy was talking about coating it in chocolate... But isn't Mercury vapor(don't think I'm using a right word for that, sorry not good at english) toxic as well?
Yes. It is vapour, but at the right temperature it is a solid. Mercury is often found in thermometers, but for example on antarctica, they have to use alchohol because the mercury would freeze. So you see, everything or at least most of the things on the periodic table, can be an gas, a liquid or solid. I hope this answer your question because i'm not so good at this ^^
If you heat anything up to a certain temperature, it becomes a gass. Mercury's meltingpoint is -38C and the boilingpoint is 356,7C
Since pure Mercury is a liquid in house temperature it can be changed to vapor. So if you're confused about the liquid thing, thing of iron and ice. Ice is a solid form for water and melts at 0C. Iron is just the same, only that it has a higher meltingpoint at 1500C give or take.
I did... And I'm still confused about all that vapourizing metal thing, dose other metals slowly vapourise at melting points as well or it's only mercury?
That would be an awesome prank, make a frozen bell of mercury and then coat it in chocolate and give it to your friend to take a bite. He would become mad as a hatter.
Tell it to all thous dead Alchemist out there who died from mercury poisoning trying to achieve immortality... Ups, you cant, why? Because they're dead XD
But you could go and dig up their bones and if the bones can answer you then you would know that yes it does provide immortality. It is possible they died in the way that we could see, but the bones are still alive.

(No he isn't.) The explosions are far more interesting. Anyone who cares about a frozen bell should get their head examined. At least with real metal it would take effort to melt it. Mercury is already liquid. You might as well make a bell out of ice. Check your lame detector, it might be broken.
Well he said it's got the wrong elasticity - that's good enough an explanation for me. And it did work - it just didn't sound very good.
It's not a physics thing, is it? Otherwise it would be called the Physics Table of Videos and that just doesn't have a good ring to it, if you'll excuse the pun :-)
Wow...! How bored must you get, as a scientist, to think about creating a mercury bell and then actually getting to do it? I love the professor's reaction, though. Hears the guy's story out, sees the object of art, then starts poking/hitting it to see what sound it makes :)) Awesome vid!
I can't help but imagine a science fiction story in which two aliens from a much colder planet discuss Earth. "Did you know that on Earth the temperatures are hot enough to melt mercury?"
I don't know if temperatures at which mercury is solid allow for any chemistry that could give rise to life, but it's an amusing thought. I do know that helium gets quite interesting close to absolute zero.
Yea, I've often thought the same thing. It's interesting learning about planets that have atmospheres made up of the vapours of metals that are solids on our planet, or that have oceans of lead as an example.
Thats an interesting question. It would be around 200K so that would mean that the chemical reactions would be rather slow and some reactions that are spontaneous on Earth may not be on another planet so they would require some energy to start up. But of course it is possible because there are an infinite number of possible compounds that could create life so finding one that could require reactions that are spontaneous at 200K sounds very possible and given that many planets are cold is likely.
I loved the explanation for why he made it; he just made it to make it.
It's sort of like when they asked a famous mountain climber (his name escapes me) why he climbed mountains and he said something like "because they're there".
I would have enjoyed watching the bell reach room temperature slowly. It would have been a melting mercury bell then. I wouldn't have expected it to ring - given that it is a property of tempering the metal not just of solidifying it. But interesting nonetheless.

It's not a physics thing, is it? Otherwise it would be called the Physics Table of Videos and that just doesn't have a good ring to it, if you'll excuse the pun :-)

And I love the coiffure of the professor :D
Thanks and all the best from Germany :)

Wow...! How bored must you get, as a scientist, to think about creating a mercury bell and then actually getting to do it? I love the professor's reaction, though. Hears the guy's story out, sees the object of art, then starts poking/hitting it to see what sound it makes :)) Awesome vid!

I can't help but imagine a science fiction story in which two aliens from a much colder planet discuss Earth. "Did you know that on Earth the temperatures are hot enough to melt mercury?"
I don't know if temperatures at which mercury is solid allow for any chemistry that could give rise to life, but it's an amusing thought. I do know that helium gets quite interesting close to absolute zero.

Yea, I've often thought the same thing. It's interesting learning about planets that have atmospheres made up of the vapours of metals that are solids on our planet, or that have oceans of lead as an example.

Thats an interesting question. It would be around 200K so that would mean that the chemical reactions would be rather slow and some reactions that are spontaneous on Earth may not be on another planet so they would require some energy to start up. But of course it is possible because there are an infinite number of possible compounds that could create life so finding one that could require reactions that are spontaneous at 200K sounds very possible and given that many planets are cold is likely.

I loved the explanation for why he made it; he just made it to make it.
It's sort of like when they asked a famous mountain climber (his name escapes me) why he climbed mountains and he said something like "because they're there".
