I mean as the top comment aptly put it, we ended up with Lincoln getting another hole in his head, so it's not much of a suprise to hear that song in the background
The copper lining would contain it unless your hole is further down large etc. Ive dissolved the zinc leaves a copper shell that's actually well able to hold its shape
@@yooowhatupribs he's referring to the zinc melting out the hole drilled. Plus the Plating wouldn't keep heat or react exactly like copper. Otherwise they'd just plate or clad other Metals for power lines vs expensive copper. They sometimes use aluminum but never for houses business etc. As they once did and discovered the al actually gains tension aka shrinking w voltage over time. Loosening from fixtures. You can plan around it to a degree like larger wire means less shrinking per volt. But it's still a copper is king kind of industry. Notice the ground cables aren't ever copper on power lines. Good stainless or galvanized steel will work.
Also, because of unclear instructions on the thermite reaction experiment, your Cousin May fell through the parlor floor today. (Penny is her roommate, and Bob's your uncle.)
That must be an older all copper penny. You can't get newer pennies that hot before the zinc inside ments and the copper skin either ruptures or the melted zinc pools in the bottom.
One of my mom's hobbies was to sort out older pennies and keep them. She had to stop bc she seriously worried the 10 jugs of them would collapse the floor of the room she stored them in 😂 now we just need that vat of acetone to survive the apocalypse.
and that year they swaped to zinc pennies so you need to weigh them to figure out if the 1982's are copper or not. 3.1 grams for copper and 2.5 for zinc. or use 1981 or newer @@Wingman4l7
@@SilntObsvr Don't worry. He will spend a lot of time collecting a bucks worth of pennies only to find out they're no longer made out of copper. So when he starts trying to make them turn red, they will suddenly disappear.
Assuming breathing acetone fumes all day is a side effect you enjoy this is actually much safer than burning candles in a cardboard box. The hot copper is catalysing oxidation but with no open flame. Spilling it would only create spilled acetone. Which would feel very cold on a cold night and you might consider setting yourself alight to stay warm
@@oddlyspecificmath Yes. Reasonably clean solid copper wire actually works a little better (pure copper instead of 25% nickel) and you can bend in any shape you like before heating.
@@TimothyEBaldwin Copper plated steel at least won't melt before it gets red hot. It seems like it ought to work, but how long the plating will last is the question. Copper plating is typically thin (cheaper that way), and the oxide that forms at high temperature isn't as well bonded to the base metal as the plating is; eventually the plating will be fully oxidized and will flake off, leaving you with (rusty, by that time) steel that won't catalyze the acetone oxidation.
"ACUTE TOXIC" That's how the National Library of Medicine describes ketene, which is a byproduct of the acetone-copper catalysis. For EACH molecule of acetone, you end up with TWO ketene molecules and TWO methane molecules. Cool reaction, but you may want to perform it under a hood. After the ketene and methane molecules are created, the reaction continues some more. The net result, after all is finished, is that one acetone molecule catalyzes with copper to create ONE ketene molecule and ONE methane molecule.
Why not just do in it a well vented area and not hover your face over it? Everyone knows some type of fumes happens when heating anything up let alone heat and something that is already not good for us as it is. Then again, too much of anything is bad for us.
@@OneAndOnlyZekePolaris One-half of a drop of acetone catalyzed with copper inside of a two-person tent is considered by the CDC to be "Immediately Dangerous to Life and Health". Toxic doesn't mean "it's not good for you", it means that every bit of it tries to kill you. If you operate such a "stove" with ventilation sufficient to be safe, then you won't be able to derive any benefit from the stove aside from direct radiation; you can't heat a tent or the like. Of course, do what you wish, but you may want to look into it a little more deeply before deciding that your rationalization is a closer reflection of reality than the warnings of the NIH (who operate the NLM) indicate. To reinforce the danger of ketene, consider that the currently accepted level of ketene concentration considered to be Immediately Dangerous to Life and Health (IDLH), according to the CDC, is 5 parts per million. That level would be reached if you were to catalyze one-seventh of a gram (0.1429 g) of acetone inside of a 4x4.5x7 foot tent; the whole penny would likely be disastrous to anyone in that space. This works out to about a half-drop of acetone conversion causing an IDLH event. I don't know the mechanism of action of ketene upon the body, but I'll take the expert's opinions regarding exposure and toxicity.
Very Kool! A light bulb illuminated in my head immediately. Like the acetone reacted to the penny, in turn, this video served as a catalyst as well, causing the light bulb in my head to react nothing short of immediately. A moment after that, I had a vision of the prototype. I'll keep yall up to date
Neat! I have a pocket heater that uses platinum that acts as a catalyst with lighter fluid and stays warm. You do have to light it to get it hot enough but then you blow the flame out and it stays hot.
This is how the old school lighter fluid fueled hand warmers work. They use a catalyst metal that oxydizes the fuel vapors so you can keep it covered in your pocket without a flame once it warms up. They last longer and im my experience they're warmer than the battery powered hand warmers sold today. They're also cheaper and can be instantly refueled on site, rather than having to be charged up.
I had a few of these from my grandparents and honestly thought they were just weird lighters; a little sad that I gave them away before really appreciating them.
Excellent, the older I get the more I'm wanting learn and retain , especially with educational videos like this. Thank you for hopefully increasing some humans I.Q. Looking forward to more of these.
It will work with newer pennies (their surface IS still copper) but IT'S VERY DANGEROUS!. Pennies after 1982 have zinc inside a thin copper shell. Zinc has a much lower melting point than copper, and the zinc could melt and drop out as a glob of molten metal into your beaker of a VERY FLAMMABLE LIQUID which would boil and splash everywhere.
The reaction products are toxic by inhalation. The copper surface of the hot penny catalyzes the oxidation of acetone. Hot copper reacts with oxygen in the air to produce a coating of copper oxide, CuO. Once formed, the copper oxide reacts with acetone, producing ketene and methane and regenerating copper metal. The overall reaction is: CH3COCH3(g) → CH2CO(g) + CH4(g)
I always thought catalysts needed flow and possibly some level of input heat, i had no idea this could happen, catalytic reaction is actually one of my favourite too
why do you phrase that like it's a problem? pennies already cost more to produce than they're worth, using genuine copper would probably end up making it worth more by its weight in copper than the value on the coin so you'd be better off melting a bunch down into ingots and selling them as scrap
@@frigid_metal9545 He didn't phrase it "like it's a problem." He's actually doing us a service, by letting us know any old penny won't do, that you need one of the pennies made before the mint switched over to copper-clad pennies.
@frigid_metal9545 the reason he said that is because the reaction won't be sustained with a new penny because only the shell is copper. The inside is zinc. You need a denser amount of copper to sustain the reaction. This has nothing to do with how much pennies cost to make 🤦🏻♂️
@@outsider344 Zinc has a lower melting point that copper and at least that I know when doing that experiment the Zinc would reach its melting point when heating it up.
I thought about using this to make a thermoelectric generator, for a series hybrid vehicle. But if it only works with Acetone and not public gasoline or alcohol, then never mind. Still, this is awesome. Thank you.
We use in Passive thermal control system (PTCS) components include: Multi-layer insulation (MLI) spacecraft from excessive solar or planetary heating, as well as from excessive cooling when exposed to deep space
Try it. And who said that you must use a penny? Anything copper should work. Even trimmings from a plumbing repair or upgrade should be okay. Let us know!
also, even if it's not pure acetone it might still work. Looks like it's just relying on the vapor pressure, and the vapor pressure is pretty linearly related to the volume percent of acetone
"Oxidizing the acetone" translated into plain English: Is burning the acetone vapors. Acetone evaporates quickly (this is why it feels cold when you pour in on yourself) and a low flash point (burns easily).
No it isn't. "Burning" the vapours yields primarily Ketene. What is actually occurring is Cu-Catalyzed *oxidation* of the vapours, which yields Methanol, CO2, Formaldehyde, Acetic Acid, Formic Acid, and Methyl Glyoxal.
@@kennethreffitt2051 Can the beaker be covered, or will running out of oxygen stop the reaction? What about a beaker and a lid with a pipette to the outside?
There is. They’re all just dangerous and not feasible considering the alternatives unless used in an industrial process and unlikely even then unless you need the byproduct for some reason.
Similar reactions catalysed by platinum and other precious metals are the basis for the catalytic converters that are used to reduce pollution from cars. The catalytic converter has a ceramic honeycomb inside that is coated in a thin layer of platinum particles, when hot exhaust from the engine containing unburnt fuel and oxygen flows through the converter the platinum catalyses oxidation of the unburnt fuel, converting it to relatively harmless CO2 and water. We don't use copper for this because it oxidises in the air and would become ineffective over time.
@@rstell589 This may also create some Ethenone (Ketene) which is extremely toxic! (almost up there with phosgene) NEVER! try this without a proper fume hood! en.wikipedia.org/wiki/Ethenone ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g9sPlMkYEIw.html
Pretty cool trick Professor. If the penny were to fall in. Careful heating the penny with an open flame acetone is highly flammable. It’s also a carcinogen.
@@spencertegtmeyer6525 Hi. You didn't explain, you repeated your previous comment. It is seen in the video that the red hot copper piece is kept amongst the vapors above the liquid. They are vapors mixed with air , oxygen, if not there wouldn't be any oxidation. Those vapors with air are supposed to get ignited at a rather low temperature. How do you explain that?
That's really cool! I am thinking that this could be used as some sort of heating element as a copper coil. I actually tought of it as a light bulb. Theoretically speaking, you could applie voltage to a thin wire to heat it and the acetone does the rest.
AQ!❤ Great idea, for a larger heater source. We can make a mini heater, that's larger of course.

Wow! Crazy Man! The heat helps evaporate the acetone and the acetone vapour is reacting with the copper causing it to heat up, etc. That reminds me of the mechanism of fire. I guess it is if, it is a redox reaction? 🔄
