You don’t need to buy the calcium acetate, as it is very easy and cheap to make. Use old egg shells for calcium carbonate, it’s basically free. Crush them up, mix with white vinegar to make calcium acetate. Filter through a coffee filter to remove solids, then let the water evaporate. The white powder is pure (enough) calcium acetate. Home-made Sterno is also a good opportunity to talk more about differences in solubility: calcium acetate is very soluble in water but not very soluble in ethanol, but when you add the ethanol the calcium acetate is suddenly insoluble, so it forms a gel.
interesting... so the calcium acetate is falling out of suspension and just trapping the ethanol between the calcium acetate molecules? i probably should've guessed as much with how much nilered i've seen over the years
This was actually awesome! I'm glad the algorithm recommended me your channel :) As a Blacksmith, I play with fire more than most. I'm now curious how some simple mesh screens could increase safety in the workshop.
Yo this actually got me thinking... Just how much heat can the screen dissipate before the screen itself melts. Like, Blacksmith heats metal to glowing red to orange. Would that overwhelm the mesh screen? If applied, where would it be effective? Near the oil quench barrel? Near the furnace door? Or simply around the tongs as a sorta heat shielding?
Could you explain the chemistry behind why adding a fast burning smokeless gunpowder on top of a black gunpowder charge makes it burn clean as a modern smokeless charge? It works I just don't know why.
that's a really interesting question on the behavior of mixtures of compounds as they combust. my gut instinct is that the smokeless powder is so much more energetic essentially being a high explosive and it basically through magnitudes of force and heat generated, as bits of that are consumed in the reaction it locally superheats those points to where the secondary byproducts of a slower black powder reaction would also react and burn to a higher degree (think about hitting a dirty surface with a blow torch and how everything organic eventually, once it gets hot enough, turns to a carbon char)
@@bobjoe1593 very good, thank you for considering my question. That sounds reasonable to me. I seem to come upon things that work but lack a good explanation as to why. I'm usually able to work things out on my own, but not always. By nature I'm very curious and want to know precisely why things do what they do.
@@zeusdarkgod7727 I'll use AI to speed up information gathering, but I prefer to solve my own problems from that point. If I run into a block I'll seek out someone with a better understanding than mine.
It would be interesting to see how layering of screens (even randomly) would improve the protection of falling jelly (and even to comparatively test spacing of those screens)
Unless I'm misunderstanding you, there isn't any room for improvement since the flame went out immediately after one screen. Any subsequent screens would just be influencing already extinguished jelly. It would probably look cool in slow motion but as far as the purpose of extinguishing the flame more screens wouldn't do anything since a single screen already achieved the goal. Maybe if they increased the amount of flaming jelly it would be able to pass through a screen with a flame but the volume of jelly required to do that (if it's even possible) would be pretty dangerous.
@ThatScrubWolf the very fine mesh screen held but the larger screens allowed gel and the flames that it carried to pass through. It probably is very dependent on the viscosity of the gel but the thought was , could a similar protective effect be achieved with more layers of coarse mesh?
That is some interesting "napalm". REAL napalm contains a mix of both Styrofoam and gasoline. It also smokes a LOT, so burn it outside or in a well-vented area. Also, it doesn't spit, unlike that jellied fuel you used.
this straight up isnt true. for starters styrofoam wasnt invented until almost 30 years after the flamethrower, not to mention that the product from mixing styrofoam and gasoline is far too thick to be shot out of a nozzle in the style of a flamethrower (+the higher pressure required) Napalm tends to be gelled gasoline, gelled gas+kerosene, or gelled diesel which is usually thinned with a solvent like benzene or toluene then an oxidizer like aluminum soap flakes or titanium oxide. the thick black smoke tends to come from added natural rubber
@@Striiiider FOURTH TIME NOW, i thought this got to you but it appers youtube thinks im a bot. i shall now include miss-spellings to the annoyance of my auto-correct and not use links or sources. TH-cam you are fostering mis-info. 1: gassoline was the first fuel in "modern" flame throwers, not this shit. 2: this is hillbilly napalm, designed for molitov cocktails and IEDs. 3; thsi shit smokes a LOT. this was origonaly better, but im throwing crap at the wall here.
SO THE ANSWER IS: YES, depending on the velocity of the fuel, and the size of the screen holes... I do believe if multiple waves of napalm.. from, bombs compromise the integrity of the screen. then the Napalm would go through.
"Testing with no expected results" the best kind of science
A science show that answers and tests questions like this is absolutely my kinda show. Love this! Actually learned something too.
It has been a winning recipe of shows for years, to bad the internet mostly trends along the Idiocracy time line.
"Good we have no kids in here" as I remember throwing firestars in titanfall 2 saying "Remember, napalm sticks to kids"

Chemteacherphil made a video showcasing that process just a couple months ago!
Sounds like an old growers tip 🌿
Criminally underrated TH-cam channel
I hate how quality channels like this are at the mercy of bipolar computer algorithm

Man, this is exactly the science show I wished was around when I was a kid. Great content!
How do you not have more subscribers?? Awesome content!
Wait until this man discovers styrofoam and diesel 😂
Wait until this guy discovers styrofoam and gasoline 😂

@@oubliette862 I tend to work in reverse of that. I will gather all information I can and then break it down even further using gpt.
It'd ve interesting if just a liquid fuel make it though the screen lit or if it also smothers on top of the screen
DANG. when the Sternos brand stuff went through the slomo looked like a blast from a pistol. so cool.

why does benzol not follow the rule? sure, it's now called benzene, but it was benzol, while not being an alcohol.
What is this wonderful channel I've just discovered? This is why I bother with TH-cam.

Hey i think you're the guy who bought an extra canopy from us.
Well, if I can't repeat this at home... What about in the woods behind my house? 😉
napalm isn't about slowing it but making it stick to things
This is great
7:41 you know me so well, it's almost like you know I'm an arsonist. If it can burn, burn it will... it's just a matter of time.
Good thing they didn't have giant mesh screens in Vietnam, I guess

I dont know if I would call that napalm 6:45 that's like the safest napalm I've ever seen.
You can put the pin back in❤
That's not Napalm.
Accuracy is important.
Naphtha is pretty easy to get.
Percent and proof are two different things.
Gasoline, kerosene, styrofoam and magnesium poweder
nice
Them poor alchemist had to endoor so much for so long to be dubbed science
Why not just the anarchist's favorite - Styrofoam and gasoline?
Im more of a styrofoam and gasoline napalm guy
Gasoline + powder laundry detergent = ?
