some time traveller is gonna scald their hand using one of these babies in the End-Carboniferous era Edit: Original comment as Pre-Cambrian era (the Great Oxygenation Event mass extinction was only 8% oxygen in the atmosphere, but still way lower than the 21% today), peak oxygen should be End-Carboniferous at 35%. Thx nerds in the comments.
@LegacyCatalyst > _That’s actually genius, why hasn’t this been a bit in a time travel movie yet_ ? Not sure if you wanted a serious answer, but I'll be "that guy" for a minute. Three primary reasons that I can see. (1) *By the ice ages, oxygen levels had already dropped* Only one of my three is based in actual science, and I'm only 90% sure that I'm right. The Cambrian era (500mya) saw higher oxygen levels--but average temperatures were also higher. So there's nowhere interesting in Earth's past that requires hand warmers _and_ also has "too much" oxygen. Climate change deniers love to lean on Cambrian atmospheric conditions as an example of "it's fine, because we've done this before." Of course, they never mention Cambrian temperatures--or that mammals wouldn't exist for 300 million years. Oxygen isn't as significant a greenhouse gas as CO2, but it's still associated with elevated temps. I honestly don't know if there were ever cold environments coinciding with higher oxygen levels, but just about everything we've seen (in both documentaries and time travel fiction) is *Big Lizard, Tropical Rainforest* It's true we've got some ice age lore in (non)fiction, but I suspect the gag would require a bit of "poetic license." (2) *It's a niche nerd joke* I actually chuckled when I read @jacksim's comment--and I expect the bulk of Chem Teacher Phil's audience will appreciate it. But the average viewer won't. The setup will take too long for the value of the payoff. Because... (3) *screen time is expensive* My brother is a filmmaker. He's always meticulously shaving five seconds here, two seconds there. Not so much expensive to produce--although production cost is certainly a factor. I'm talking about final project runtime, e.g. having a short film over 20 minutes is a cardinal sin. And the attention span of today's audiences is largely driving runtimes down even further. Having done music for a couple of them, I've fallen in love with lines (or entire scenes) in drafts that sadly are excised from the final project. I'd be extremely impressed if someone can write a setup that adequately articulates the relationship between the rust, heat, and ambient oxygen content--and then films a joke (likely a quick visual gag?) that justifies the time burnt † on the explanation. This short is 31 seconds--and that's probably too long for a series that's not intentionally educational. My vote is if ArcOsprey can overcome #3 that this idea gets included, because it's a great idea--but I'm not optimistic. Sorry to be the downer if it doesn't work. † no pun intended
That's very interesting! They hand these out at work and I cut one open at the end of the day out of curiosity. Had no idea what was in it, definitely looking like metal shavings!
It's funny that I came across your channel. One of my new years resolutions is I want to start relearning basic highschool information. First on the list is to familiarize myself with (again) and then remembering the periodic table!
I remember doing this when I was 12 or 13 in the Boy Scouts, and then in all of my infinite wisdom, I found myself doing it again in FTXs in the USMC. Between hand warmers and coffee, we could conquer the world.
I didn't even know handwarmers like this were a thing until I was an adult. It was this weird alienating revelation. "People buy disposable packets to temporarily keep their hands warm? What?"
This reminds me of the demonstration my instructor did when we were learning to flame-cut steel. He preheated and started the cut, but then turned off the acetylene part-way through and finished the cut just with the reaction between the molten steel and jet of oxygen.
@@MintBiscuitlol it's relatable tho when I first started using tumblr after taking a break from twitter my brain always called the posts there as tweets and reblogs as retweets. Too much twttter did this to me
i think it's interesting to think of how they probably researched to find ideal quantities for ambient conditions. maybe it's a simple calculation or maybe not. would be interested to know how they figured it out.
I googled this during the last snow storm and it made me so unreasonably happy. But also it made me very concerned for my car to know just how fast iron can rust
So basically it just encourages the hell out of oxidation, so much that the process of rusting generates enough waste heat that we can actually feel it? Thats crazy
I once had some random food package contain a small version of these to trap any oxygen that leaked into the bag. It turned pretty warm donce the package was open
Bruh for being an outsider is crazy to see what things exist in the US, first was the thermite coffee can and now hand warmer? Are really amazing to hear for first time
Here's a pro tip for all the people who's cars wouldn't start in that extreme cold snap we had a week ago! If your car has trouble starting due to a weak battery/ bad corroded terminals in the in the super cold weather, you can open a 2 pack of those suckers... Then place one on top of each terminal/ connector. Then proceeded to let warm up the terminals and battery for about 5 to 10 minutes... Then BOOM your car will start right up!!
I doubt some hand warmers are really going to substantially affect the temperature of a 40 lb lead acid in 5-10 minutes. Maybe you'd see a degree or 2 in like 45 minutes. Just get a jump pack, they're cheap and worth it.
The fact that finely divided rust is used to make thermite should give you a sense of just how exothermic rusting can get if allowed to happen fast enough. Pyrophoric iron powder is also an example of this.
that s interesting. I always thought it was more like a quicklime reaction but wondered how they kept it from getting too hot. This makes a lot more sense
I love these hand warmers. The military had some 40 years ago but they weren't as good as these. I try to remember to take these with me to the hospital because I am often very cold there plus if I have one in my hand it makes it a lot easier to get blood out of my arm, and if I am having surgery, I put the foot ones in my socks and and hold on to the other ones until I fall asleep. 😊
This is really interesting to me because I work Maintenance at an ice rink facility which uses calcium chloride brine to chill the floor, and anything that stuff touches is not extensively cleaned immediately it will be ruined with rust.
Its why you can slow or pause the reaction a little bit by putting them in a closed container, once the iron reacta with all the oxygen in the container it cant continue to oxidize
Thank you for doing this! I actually found out how they worked and considered putting them in oxygen myself, but then I realized what if it goes nuts on me and starts a fire or something, so I decided against it. I now have my answer. Still not trying it though haha
I'm homeless, and I use heatpacks that are meant for reptile transport. I put one or two in my sleeping bag when it gets cold. So comfy to have warm feet 🤗
Fun fact; until recently, most firearms were finished with 'bluing', which is intentionally allowing an even, thin layer of black oxide to form on the metal.
Fun fact, you can turn off the acetylene while oxyacetylene torch cutting, and use just pure oxygen to continue cutting/melting the steel. That's how strong this effect can be.
I think they need to be kept where there's humidity otherwise they dry out and stop working(when activated). Like in a pocket close to your body so your sweat keeps the humidity up.
i didnt know rusting wqs an exothermic reaction, but it makes sense its oxidation, thats the same reaction that takes place when we burn things. why are some reactions exothermic and some endothermic? i remember watching a small lecture from the royal academy about this, it had something to do with entropy and energy. the two rules beling the universe tends towards minimizing energy and increasing entropy, increasing entropy makes intuitive sense in the case of gasses diffusing and temperature equalizing, it simply state that stuff thens to spread, and because there are many more way for something to be disorganised than for that something to be organised, it tends towards being more disorganised. This is also where you get the phrase "life on earth is a thermodynamic miracle" but i never quite understood minimizing energy, and couldint explain why that is, other than, its just the way it is. any system tends to prefer a lower energy state, maybe its too fundamental to explain in any other way, other than its just the way it is. i think these two properties of our universe, entropy increasing over time and state energy minimizing, are what dictate wether something releases heat or absorbs heat into/from its environment. things that lower the energy are bound to release that lost energy in the form of heat. i dont remember what causes cooling... i wonde rif i can reason about it, well it must take energy from its environment instead of giving it, that was the explanation! the professor asked the question: why does it do that, even though it requires energy to do so? why do endotermic reaction able to occur? and the answer was entropy, it was because even though the energy in the system was increasing (stealing heat from the environment) entropy was still increasing i belive the example given was an ice cube melting, ts an endotermic thing (i dont think its a reaction... maybe it is a reaction, because the hidrogen bonds between the water molecules are weaking, even though it doesnt have a chamical equation) and it also increases entropy, that was the secret sauce, to cooling off the environment, does the thing result in increased entropy. man, this comment is not for the weak of heart, what a long thing ive wrote.

i didnt know rusting wqs an exothermic reaction, but it makes sense its oxidation, thats the same reaction that takes place when we burn things.
why are some reactions exothermic and some endothermic? i remember watching a small lecture from the royal academy about this, it had something to do with entropy and energy.
the two rules beling the universe tends towards minimizing energy and increasing entropy,
increasing entropy makes intuitive sense in the case of gasses diffusing and temperature equalizing, it simply state that stuff thens to spread, and because there are many more way for something to be disorganised than for that something to be organised, it tends towards being more disorganised. This is also where you get the phrase "life on earth is a thermodynamic miracle"
but i never quite understood minimizing energy, and couldint explain why that is, other than, its just the way it is. any system tends to prefer a lower energy state, maybe its too fundamental to explain in any other way, other than its just the way it is.
i think these two properties of our universe, entropy increasing over time and state energy minimizing, are what dictate wether something releases heat or absorbs heat into/from its environment.
things that lower the energy are bound to release that lost energy in the form of heat.
i dont remember what causes cooling...
i wonde rif i can reason about it,
well it must take energy from its environment instead of giving it, that was the explanation!
the professor asked the question: why does it do that, even though it requires energy to do so? why do endotermic reaction able to occur? and the answer was entropy, it was because even though the energy in the system was increasing (stealing heat from the environment) entropy was still increasing
i belive the example given was an ice cube melting,
ts an endotermic thing (i dont think its a reaction... maybe it is a reaction, because the hidrogen bonds between the water molecules are weaking, even though it doesnt have a chamical equation)
and it also increases entropy, that was the secret sauce, to cooling off the environment, does the thing result in increased entropy.
