I make a 'gold' play button out of the most reactive gold colored material I could find. making caesium: • Isolating Cesium Metal Help me make videos by donating here: / codyslab
According to wikipedia, the price for cesium is $11000 per kilogram, divided by 1000 is $11 per gram. If you have 84 grams of cesium, that means you threw $935 dollars into the pond and watched it explode. That is well worth the money...
@@WAVtbl As he pointed out, listed price is no way near the actual cost. The reason it cost so much to order Cesium is the insane shipping and handling that comes with a material that blows up if you look at it wrong.
**3 years later** Hi guys, Cody's Lab here. To celebrate 10 Million subscribers, I'm going to create a highly radioactive play button. *dips finger in mold* Well, I have 6 fingers on this hand now, but I'd say it's coming along nicely.
@@spamlord7570 Its used in Lithium Ion batteries because it's good at being used as a battery. You really dont want to touch lithium, which is an Alkali metal (reacts with water). Not only is it toxic a degree, but since you are 70% of what it reacts with, and your body sweats out water, it's probably best to avoid physical contact with pure lithium Edit: fixed spelling
oh thank goodness im so glad its a joke that skin explodes on contact with water i thought id just been getting lucky my whole life havent showered or washed my hands or had anything to drink for a week so thirsty ty for helping me out here
Really happy to see this Cody. I knew it wouldn't take long for you to hit this mark back when I found you at around 20k. It's well deserved! Here's to 10MM!
I'm a welder and have to agree although admittedly I sometimes get lazy and will do a few quick welds bare handed but never a good idea I have several scars from burns do to my own stupidity
Hi Cody, I have a great idea for your vaccum chamber. As we all know small devices produce some heat while working, but that heat quickly disappears in the air. What if you leave for example a flashlight on something which insulates heat from the walls. Will that overheat or it will radiate heat as an IR light like spaceships do?
Merging two atoms is fusion not fission. Fission is splitting an atom. If he manages to fuse two atoms, he'll become the most famous person alive and solve all of our energy problems. Cold fusion has been sought after for many many decades.
He probably mistyped fusion, he only used one "s" and "u" is next to "i" on a keyboard, making it very likely that such a mistake would occur. And fusion describes the process of multiple atomic nuclei coming close enough to form a new atomic nuclei not merge.
The half life is far to short, and it is far to rare, so it's impossible to have a measurable amount for more than 20+ minutes. It's also highly radioactive.
Lol god I always get such a nostalgia burst when I hear that terribly mixed opening jingle for old Cody's Lab. I cannot believe he never fixed that. Why didn't he fix that?? hahaha.
People might think that he doesn't know science but he probably wastes a lot of money for us to watch this video while he has to go through a bunch of trial and error.
someone more knowledgable than me said with the impurities he maybe got it to be worth 3-3.5k. He also needs tons of permits to sell the stuff legally, can't ship by air, and need to sell it to an approved buyer.
Right, well there's a number of things going on here. First, the cesium he distilled (from the much more stable and safe CsCl) isn't particularly pure, hence it wouldn't be worth as much. Purifying cesium is incredibly dangerous and expensive to do. Second, transportation. Transporting purified cesium is incredibly dangerous if not done properly and expensive in general. Third, since its such a reactive compound, I imagine you need all sorts of permits and licenses to sell it, not to mention taxes for this sort of thing, so even if the cesium Cody made was pure, and he could figure out how to transport it, he couldn't sell it to anyone.
You're quite a talented bloke Cody. Keep up the enormously entertaining videos. I'm surprised you have so many subscribers, being such a niche audience. Well done. Regards from one of your fans from England.
walking cows is actually pretty common in Germany... once I worked in a more rural area and if I went home from work it did happen quite often that I had to wait for the cows to cross the streets first...
I heard somewhere that it's expensive because it's very hard to safely ship it due to it's reactivity. You can really only make it, and keep it where it is.
Very impure. Lots of cesium oxide, silicon, and chlorine can be found in his play button. I'd say there's far, far less than 84g of pure cesium in the play button. Plus, the amount of pure cesium in the sample would rapidly decay over time given the lack of proper storage conditions.
So close to 2 000 000 subs!!! You can be proud of yourself Cody, cause we are! In fact, if we include the ones who unsubscribed over time, you already reach 2M different subs, just not at the same time.
@@leomadero562 found the antivaxxer who does not know that he/she (along with flat earthers) are of the very small group of ideologies that are objectively and factually incorrect.
@@settratheimperishable4093 well i meant that unless you have the exact thought process and know about the meme it makes no sense, especially on such an unrelated video
100 grams of nearly pure caesium went for $535 two decades ago according to a thirty second google search. (I could probably find more recent data but im lazy) which is about $830 today. No where near $3360
Colin D I didn't look it up cause I don't really care but if I remember right Cody said it was worth more. I may have misheard, I don't think so but I'm not watching the video again. I'm sure I will never own or sell either.
More like $3,500. Current price is $40.80 per gram (assuming 99.9% purity) - which i dont think Cody would have achieved due to the unreacted lithium and other contaminants. But still, not cheap.
He didn't buy cesium. He bought cesium chloride and converted it to cesium metal. A quick look on ebay, 50 grams of CsCl can be had for $25 right now. Without doing any math (to find out exactly how much is needed for an 84g play button), in Cody's first distillation attempt he added 200 grams, so $100. Another peek on ebay, 20 grams of Lithium is another $15 or so. Add in some steel pipe, a broken flask, mineral oil, welding rods, and energy, and yep, you're looking at about $200, not $8000. Biggest problem with having $3000-whatever worth of cesium is finding someone that would actually want to buy it, IF the government would even let him sell it w/o all sorts of licenses, taxes, fees, handling requirements, etc. His best option is to throw it in a lake.
That's because francium doesn't exist in quantities greater than an atom at a time. It's too unstable. Also, how do you know it's more explosive than caesium?
Francium is also super radioactive, it would be awesome if they could create a lump of it, but there going by reactivity relative to the other alkali metals there's a safe assumption that the reaction would be greater, but i doubt by much.
James Watson Well, I mean the lower elements just smoke or nearly explode. Cesium explodes on contact with water, creating an explosion that destroys glass, and Francium... It is unknown but the explosion would probably spit out radioactive material, and destroy it's container. I mean, if a lump WAS created, It would radioactively decay into another element. Good luck getting it with it poisoning you nor it decaying
You need to degas the RTV for your mold before casting. Just run it in a vacum chamber for a few minutes until it stops foaming. Much better results with no voids, etc.
Cody, pleace there is a salt of gold and cesium called Caesium auride. and its see through. it is a salt not a alloy. i have talked with my chemistry teacher about making it. i bought the gold 0.1 gram but haven't got cesium. cody please do it you are the only person i know who could or would do it.
i've also done stick welding with bare hands and actually it works. Unless you get a hot spark on your hand that hurts a little but overall it works just fine.
it really depends on how long you're gonna weld with it. you can end up with first degree burns from the welding, not the heat but the 'radiation' i dont know the english word. the rays.. what ever im a welder burned my chin because my weldin helmet didnt have a leather slap on it.
The amount cesium goes for depends on purity. I've seen estimates say $200, though that's what he spent on products to distill the cesium he had (which wasn't in its pure form.) So it could truly be anywhere from a couple hundred, to a couple thousand dollars.
As a brazilian from Goiânia I get chills just hearing the word Cesium. In 1987 we had the worst radioactive accident outside of a nuclear powerplant in history. Lots of people died
TheMagicalC that would certainly top a cesium button. But I think it might be slightly illegal and almost impossible to obtain aprox 3 pounds of U-235.
I started watching you just for fun, back a few years ago - you just basically happend to be in my recommendations.. Now your like 930.000 subs bigger since then.
You are the coolest dude ever and I would be humbled and honored to learn chemistry from you in person. The videos are very educational but they obviously can't show everything
Solid lithium play button. To stop the annoying reactivity, just dunk it in bucket of water a few times! The water will help form a protective layer of oxidation, so the lithium stops reacting with everything. :)
