+Cody'sLab That would be a great video, both for exposure of that problem more, and also just for showing off. Imagine pulling out some lead from 5 or 6 gallons of Flint water
+Cody'sLab Cody. my univercity in Amsterdam has water from flint for research and students are allowed to take it with them. i can send you some if you would like it.
+Jason Patterson I can detect lead down to about 500ppm so to detect 10ppm I would simply evaporate down 50X so that I can detect it. if its down in the range of 10ppb I can still detect it but it will need much more evaporating.
He’s likely referring to the fact that the shape of the crucible resembles a bomb calorimeter. It’s a device that burns materials in order to determine the amount of energy they release. They’re the same shape
I used to work in a lab and sometimes tested for lead in paint samples. I found that lead paint comes in a large variety of colors, but you could generally tell it was lead based by how brittle it was. It's amazing that you were able to get so much lead out of such a small sample. BTW we also testing for asbestos in building materials. In a house of that vintage you can find it in drywall joint compounds, popcorn ceiling, flooring tiles and glues, linoleum backing, heater insulation, cement siding, under sink coatings, etc. Since you have access to a geology lab you can use polarized light microscopy to identify the different forms of asbestos. 90% of what's in the home is chrysotile, but you might find some crocidolite or amosite in the cement siding, or heater insulation. Might be an interesting follow up video.
The amount of lead recovered from just that little bit of paint is quite scary when you think about how much old paint we are surrounded by, especially coming from England where every building i step foot in can be traced back to the dooms day!!
A fun fact about lead based paint is it keeps colors vibrant longer due to the low reactive nature of lead. Even after all these years, the paint is still a bright white.
+jonah castro Lead is not dangerous like this... he was outside, in a well ventilated area. The lead was not overheated. The amount he did touch was extremely small and he didn't touch it for long at all. He would experience no effects whatsoever. The problems that come with lead are when kids were constantly surrounded by lead (like in the paint), which would inevitably get in them.
I'm 90% sure this is his own home, not the ranch, which is in a neighborhood. So a cop wouldn't be trespassing (unless it was his backyard where it was filmed)
Hey Cody I'm twelve (Almost 13) and I've been watching you for a while and you have taught me a lot about a lot of science and I just wanted to say keep up the good work!😄
That's why young kids eat old paint, and can cause mental retardation (which is a real medical term for somebody with a mental disability, btw. It's not meant as offensive or demoralizing. Doctors have no time for political correctness.)
***** Lead is legitimately bad for you, so I'm assuming you're joking. Normally, people can't take a bit of name calling, but you'll have to try harder.
***** At least I'm not a furry, if that counts for anything. I may be a bigot, but for the right reasons. I never pass judgement for skin color, or race, or religion. I pass judgement for someone's past and present actions, and whether that person is counted as "good" or "bad" is not up to me, but to the general public. You yourself are a bigot, too, because the literal definition of "Bigot" is someone who is intolerant to anyone with a differing opinion" so you know what? Everyone is a bigot to a certain amount. That amount, however, comes down to how you were raised, and I was raised to understand science. I am starting to believe you are an internet troll, and I am bigoted towards trolls, so before either one of us starts a flame war, have a nice night, because it is 9;50 Eastern/Atlantic time.
Hey cody, be carful when pouring molten metals over concrete. its much safer to pout over a cat litter box with some sand in it. hot metal + concrete can cause the water in the concrete to flash steam, which can cause the top layers of the concrete to explode up at you, sending hot metal your way. the amount you had there was no real threat, but if you are doing aluminum casting, its something to be carful of!
Hey Cody, I am watching from germany and sometimes I have no idea when you are using the English names of the chemicals. Could you maybe show the periodic table Letter in your videos whenever you are doing a test ? Would be awesome. Thx
+FrozenXD Thx alot. Yea lead was easier because I know that there was a toxic paint which contains pb. But sometimes (for example gold extraction) he is mixing stuff together and I have no idea what he is using :)
Man, you always do such a great job with your videos, and I really enjoy the different intros. you can tell you put some work into it, and I just want you to know that it's all genuinely appreciated!
Thank you for adding the ending bit. As someone with the mind of a scientist, and a cat, I wondered how the test would do on new white paint. Not saying I doubted it, but it is just cool to have closure.
After watching your videos I'm starting to find myself watching more science related content on the Internet. I'm glad you make it seem so fun, I'm sure a lot of people appreciate the work you do in filming it all in your own home. Well done on the lead by the way, I now have some idea of how much lead per quantity of lead based paint I may be handling at least after an average extraction. :-)
Mike again Cody loved the video remember doing the same basic thing with my neodymiums and some cereal rich with iron taking the iron out of it it was fun I was just bored that day
When I was younger my father got me some fishing gear. We never actually went fishing because he was always working so when I was bored I would occasionally go through the fishing gear and plan out using it when we finally would go fishing (we never did). I found the sinkers and they were made out of lead. Of course I didn't know they were sinkers and simply saw metal balls. I then had the brilliant idea of biting them and I did. The metal was very easy to slice with my teeth. I don't know if I ever ingested any amount of lead but I definitely chewed on lead. I don't know if it had any effect on me.
Yes you can test for Lead without a kit. Lead has a sweet taste. That's why kids will eat paint with Lead in it. You should take proper safety precautions when working with Lead. Gloves and mask when handling Lead and a respirator when you incinerate it. I have a deleading license in the state of Massachusetts and it is illegal to remove Lead paint with a heat gun because of the fumes.
+Philip Bender Only soluble lead has a sweet taste, most lead such as the oxide, sulfate or carbonate don't dissolve enough to affect your tastebuds. (Until they reach your stomach.)
Hi nice vid, can you try to check wooden frame of window for presence of lead? It''s interesting to see that led from paint was migrated in to the wood and possibly how deep if...
CODY!!! LAST NIGHT, I SAW YOU ON SCIENCE CHANNEL. YOU WERE ON OUTRAGEOUS ACTS OF SCIENCE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Good job man!
I have a question... what precautions do you take to prevent a heavy metal intoxication? Or do you just say that there won't be any major health effects for you in those tiny quantities that you work with?
+danger usb - All you need is an inquisitive mind. The internet may be littered with a lot of trash, but there's now, more than ever, more useful information than there has ever been. You don't have to discover anything new. As Cody has proven, it's often more interesting when you do things for yourself. If there's anything you've ever wanted to do, you'll likely find a wealth of info out there on how do it it safely, if it can be done. As someone that casts their own lead bullets from range scrap (used bullets I pick up at the gun range), I've always loved playing with molten metal. Recently I stumbled onto "lost foam casting". I'm currently preparing to melt down a heap of aluminium cans I've collected and cast them into the shape of a slingshot. I have no practicable reason for doing so other than for my own amusement. Should be fun :-)
Actually Cody as I understand it, first Zinc white and later Titanium dioxide was, and still is used to make paint white. Lead was used in all paint, not just white. It has really great properties to make great paint. Only thing, it's toxic. But it speeds up drying, it makes the paint more water and UV resistant to color fading, and more opaque. It is a fantastic material for making good paint of all colors. If you have old paint, it's guaranteed to have lead in it, it was universally used. And terrible for our health.
I really enjoy your videos! You've peaked my interest in a lot of different areas. If you could do any videos on batteries or anything that has to do with learning about electricity I would enjoy that.
Hey Cody, I've made my own charcoal crucible with an old flowerpot-based furnace, but it's pretty unwieldy and imprecise, and I'd like to get an electric one. Which one is shown in the video? Would you recommend it?
+jackson neder don't even bother. lab equipment can cost you thousands of dollars. However, you might be lucky and pick up a used one (like the one cody has, i assume) for cheap.
How much do those tests cost there? I tried finding something similar, but all I can find is stuff for testing water. I have some really old kids doll furniture that I would like to give my children, but want to test them first, and buying the chemicals will cost me a lot (though I then have for like 1000 tests or so, maybe I should sell some)
It's like you know how everything was formed, what every material is made of. Every human should be able to do that, we don't know this planet as much as we should considering well, we live here
I'm so glad I found your channel! I've become a huge fan very quickly and have almost watched all of your videos. Have you ever thought of getting some custom Cody's Lab t-shirts to sell to your viewers? I certainly would by a few! THANKS for your outstanding videos and awesomeness!
G'day, Yay Team ! That's a cool bit of work Cody..., well done... Segue...; Back a few videos ago, when you were firing Explosives in your Mine, you couldn't get the old Portable Blasting Generator to trigger the Detonators, did you say that it was only giving 12 Volts ? Yesterday my son (the Auto Electrician) showed me a WW-2 Blasting Generator which he'd found in the Roof-Space of his Workshop, and it's pulsing at *over 30 Volts*...; so, maybe yours has a Commutator problem & it's running at 30% efficiency, perhaps ? Just a thought... Have a good one, ;-p Ciao !
Lead paint was only partially banned, lead paint still exists in artist paint in the US (for whatever ridiculous reason), it's banned pretty much all over the world except the US and Africa. In the US it's called Flake White. If you touch it with bare hands, you will eventually die from it. It's not instant, but it happens over time.
1963-built homeowner with a young child here. You can get rid of this shit using Peel Away 1, available from Grainger. I strip it off and then wipe the wood and surrounding area with TSP and hot water
Dear Cody, Got a request. Could you ad a sense of cost in your video's? I mean you are getting gold, lead silver and what not from all kinds of stuff and it seems pretty cool. And it (specially the gold I guess) represents some near substantial value. But is is economical? I doubt it but how much it isn't economical I have no clue. How much do your experiments actually cost? How much money have you put in that mine and (as a comparison) how much should it yield before you even reach the break even point?
+heyou fracking is great because it greatly reduces the number of wells that need to be drilled. This means that when fracking you actually have less of a chance of contaminating ground water because you pierce the aquifer less often. of course there is always a chance of environmental damage when drilling for oil and gas so I would rather see no oil wells drilled at all.
I seems as though the sample you got from your window sills was small, and possibly painted over many times with more modern paints using titanium dioxide as the white pigment and latex, or other resin, plastic as a binder, many white paints in the past were pure lead oxide for the pigment along with the binder, typically linseed oil. I wonder how much pure lead can be isolated from pure lead oxide? since the formula for lead oxide is PbO, would it be safe to assume equal amounts of lead to oxygen?
There goes Cody, making me feel like an idiot again XD, lol, but Cody HAS taught me A LOT!! I love learning about all sorts of sciences on his channel!! He should definitely make a series where he teaches us stuff!!! Like if you agree!
So, hey. My cousin tells me that you can tell standard latex paint from lead paint by noticing the the difference in how it chips up when chipped off. I think he was saying that lead paint is more brittle, but I have never had to deal with old houses so I only know one kind.
Cody, you should try to get Bismuth from Pepto Bismol. It has bismuth subsalicylate and it'd be pretty cool to see how much bismuth you could actually extract from it, especially since Bismuth is such an interesting/pretty metal.
Gareth Dean oh, well still lead tastes sweet xD if you use lead instead of sugar i can promise you that you won't putt on much weight for the rest of your life!
origamigek ... if you REALLY want to i guess you can taste it, but be sure to wash your mouth multiple times over multiple hours with different liquids
origamigek I'd keep a wash of EDTA handy. I mean, I guess you could do it and rinse immediately after, you probably wouldn't get that much of a dose. But you'd still be getting a dose and one that won't shift easy.
When you have a cap on a crucible like that, does the air inside expanding as it heats cause it to leave the crucible, so that the lid sticks to the crucible once you cool it odwn due to a vacuum?
I would love to extract lead from water so if any one lives in flint please send me a pm so we can arrange to have about a gallon sent to me.
+Cody'sLab That would be a great video, both for exposure of that problem more, and also just for showing off. Imagine pulling out some lead from 5 or 6 gallons of Flint water
+Cody'sLab i live in MI but too far from flint. It would be awesome to see
+Cody'sLab Try extracting titanium from white paint. Titanium dioxide is a common white pigment.
+Cody'sLab Cody. my univercity in Amsterdam has water from flint for research and students are allowed to take it with them. i can send you some if you would like it.

I can detect lead down to about 500ppm so to detect 10ppm I would simply evaporate down 50X so that I can detect it. if its down in the range of 10ppb I can still detect it but it will need much more evaporating.

The amount of lead recovered from just that little bit of paint is quite scary when you think about how much old paint we are surrounded by, especially coming from England where every building i step foot in can be traced back to the dooms day!!
I've also heard that lead paint was legal and available in England, and Canada, into the 90's
A fun fact about lead based paint is it keeps colors vibrant longer due to the low reactive nature of lead. Even after all these years, the paint is still a bright white.
Welcome back to "what dangerous thing cody does today!"

And sanding lead paint of course and breathing the dust.
lol
Lol, if I were a cop and came across someone crouched down on some stairs with all that stuff I would've thought you was making drugs or something.
Lol well to be fair if you were a cop and came across these particular stairs you'd have been trespassing for a mile or so already. =P
I'm 90% sure this is his own home, not the ranch, which is in a neighborhood. So a cop wouldn't be trespassing (unless it was his backyard where it was filmed)
Did you taste it to REALLY make sure it was lead?
Hey Cody I'm twelve (Almost 13) and I've been watching you for a while and you have taught me a lot about a lot of science and I just wanted to say keep up the good work!😄
Why am I constantly amazed at how amazing your videos are? You would think that by now I wouldn't be surprised - but I am. That was amazing.
Pretty cool way to visualize the ratio of lead content to total volume of the paint, good experiment!
Can you get lead from a Led Zeppelin album?
No, but you can get cancer.

There more like chips, but lead is supposed to be sweet.
That's why young kids eat old paint, and can cause mental retardation (which is a real medical term for somebody with a mental disability, btw. It's not meant as offensive or demoralizing. Doctors have no time for political correctness.)

Cody, maybe you could've frozen the paint chips with liquid nitrogen to make the paint chips more brittle and then crush them in to finer pieces?
+LongJohn Vllasaliu
see now thats an idea!
+LongJohn Vllasaliu he also could have just used a mortar and pestle lol.
Ampix0 or both
the paint chips don't contain any water of crystallization, so I don't think the nitrogen would of been a reasonable use.
+Ampix0 That would make your mortar and pestle unusable for pretty much anything else, cause lead poisoning.
200,000 here we come congrats cody love your work.
I love the metal lead, really cool properties. I have a cube of metallic lead from luciteria and it’s epic.
That little graphite crucible is so adorable.
Hey Cody, I am watching from germany and sometimes I have no idea when you are using the English names of the chemicals. Could you maybe show the periodic table Letter in your videos whenever you are doing a test ? Would be awesome. Thx
+Testogaming This is lead, which is fuhren in german, symbol Pb
+Testogaming lead = Blei
+Stan Theman fuhren XD Eine Fuhre Blei bitte!
+FrozenXD Thx alot. Yea lead was easier because I know that there was a toxic paint which contains pb. But sometimes (for example gold extraction) he is mixing stuff together and I have no idea what he is using :)
+Testogaming I agree that he should use the Symbol for the chemical. And I'm an English speaker, It would just be easier.

what kinda of furnace to you use for melting your metals iv been looking to get one i dont know where to start
wasn't it originally an oxide?
hi, i was thinking about the outro you made with liquid nitrogen in the frying pan. how will that look like with a cube of dry ice?
That was cool. I wonder if any gold or silver is present?
You're the best Cody!!!
so... I was wondering... is it possible to extract uranium from uraniumglass?
Your on a roll cody
So, hey. My cousin tells me that you can tell standard latex paint from lead paint by noticing the the difference in how it chips up when chipped off. I think he was saying that lead paint is more brittle, but I have never had to deal with old houses so I only know one kind.
Your ending music is the kind of music I like :).
hey Cody, where did you get your furnace?
What furnace did he use I'm looking into buying a new one
Love your videos! I just signed up on patreon.
Cody, you should try to get Bismuth from Pepto Bismol. It has bismuth subsalicylate and it'd be pretty cool to see how much bismuth you could actually extract from it, especially since Bismuth is such an interesting/pretty metal.
where did you get that furnace from?
Maybe the interior has been repainted so you should shave off a bit? Or was that checking the interior at the end there cutting into it?
Why dont you extract more lead?
if you taste the lead paint it should kinda taste sweet.
this is not recommended obviously.
+BlueBeamProductions Only soluble lead is sweet, most lead paints are rather flavorless.
Gareth Dean oh, well still lead tastes sweet xD if you use lead instead of sugar i can promise you that you won't putt on much weight for the rest of your life!
I actually made some lead acetate recently.
I'd like to taste it and verify it's sweetness, but I feel like that's a pretty bad idea.
origamigek ... if you REALLY want to i guess you can taste it, but be sure to wash your mouth multiple times over multiple hours with different liquids

I'd keep a wash of EDTA handy. I mean, I guess you could do it and rinse immediately after, you probably wouldn't get that much of a dose. But you'd still be getting a dose and one that won't shift easy.
When you have a cap on a crucible like that, does the air inside expanding as it heats cause it to leave the crucible, so that the lid sticks to the crucible once you cool it odwn due to a vacuum?
I doubt that it makes a perfect seal. It is a clay/graphite mixture and has a rough surface.
Is your graphite crucible fragile?
Why are you working in a stairwell?
