Actually, that perfectly sums up this video: NUT-NUT-NUT-NUT-NUT-NUT-NUT-NUT-NUT-NUT! Seriously, you managed to be informative and professional, whilst still being incredibly entertaining and keeping your unique style. Great Job! I was also very glad to see that I'm not the only human on Earth to have such bad luck in the lab. (This sounds really mean but I honestly don't mean it to be!) Sometimes it really does feel like I am simply unworthy to be in the lab at all, because the chem-gods keep punishing me in the most impossibly sadistic ways...
@@ExplosionsAndFire; Oh no I didn't mean anything remotely as noble as that. I meant stuff like chucking things and having them bounce into your flasks. Worse still, I was also *THAT GUY* in uni; while trying to work up a reaction late one night when I was still an undergrad, I even did the unthinkable (yes I am ashamed to admit it); I left the stopcock open when I went to add my gravitationally chromatographed concentrate back into the sep-funnel... Still, thank you for your kind words of encouragement! I have always been more at home with the theoretical side of things, although I absolutely love practically doing the reactions myself (go figure!). Personally, the ultimate reward for me comes from finally isolating a weighable amount of pure crystals from an initially intractable brown mass.
I burnt myself burning the vapors in a 94% ethanol bottle. Makes a small blue jet. And it burns through the epiderm so it does not show but your nerves are telling you NO.
I love how funny you are well still being really professional and educational! This is what more kids need to watch to be interested in chemistry ! School just chokes a textbook down your throat. Keep up the good work man
I am so glad I was skeptical of the claim nitric acid would catch nitrile gloves on fire. SOP was latex under nitrile for small scale stuff that didn’t require full acid gloves. We had full strength hcl, nitric, hf, sulfuric and acetic on the acid side. Dozens more bases.
I just found you. You are a freaking hoot man and I love this as both a chemist an chemical engineer. I love the humor but thrown in with some real science and mischief.
Interestingly enough nitroglycerine and ethylene glycol dinitrate can both be used as plasticizers. They work really well for PETN and ETN. They are far from perfect and I imagine they add to the sensitivity but they are an energetic plasticizer/binder.
I found this channel by mistake, watched a couple of videos and you have definitely won me over dude. I had to subscribe. I love your style of high quality chemistry shitposting.
If anybody is wondering what he flashed by the end of the video while regretting why the f did he he tossed the playdough into the beaker(accidentally), let me explain. Remember the ferrate stream on his 2nd channel, making a purple iron 4 solution all throughout the night when you should be fckng asleep, the play dough messed that up by reducing it. And trust me he is as disappointed as we are. Fck that dough.
Hey Dude, as someone who comes from this industry, I was an ATO in another life, this is one of the very few channels that doesn't talk total bull when it comes to explosives. Also it's funny. Well done sir
Just a heads up for anyone else interested in this synthesis a lot of papers say if you are going the sulphuric acid route to dissolve the pla into the sulfuric acid and then slowly add the acid to the nitric acid
At 7:27 we have a Chem-Player ant. Took me 5 minutes to get to read what you had at 9:34. Pewdepie indeed! I came to watch you. Good amusing vid. Thanks for that!
You are amazing man. Please tell me you back up all of your videos. They are going to go away at some point... 10/10 informative, fun, & thought provoking... You could actually go places with this "Personality"
PfunkNH I download every single video, don't want to loose loads of great information again. F youtube for closing Ex&F... glad that he uploaded some old footage.
I can definitely see the difference you have come from when I first found your channel when I was looking for how to make dichromates from stainless steel, which you had done. I subbed back then, think it was 2017, but your video was a bit older. Your education has skyrocketed since then. I do apologize about recommending cubane, only because it seems HARD AF. I merely figured if anyone could do it it was you, nurdrage or nilered. Keep shining, doc.
Hi as usual interesting and entertaining video; stil I have to add my 50 cents and energetic chemical expertise... I had to bring some light and truth onto your video that seems to disqualify polymer or arge for their ban... From what I was able to understand and gather from infos about high energetic materials: First about molecular weights: MW M1 < MW Mx < MW pM A) If you go from monomer (M1) to multimer (Mx) and finally to polymers (pM) you usually end up with the following sequence of density d(M1) < d(Mx) < d(pM); this comes from my observations out of detonic parameters from hunderds of explosives (at this time after more than 30 years of study I couldn't find one single example that goes against my theory and conclusions). Most of the time density increase (contraction due to Vanderwaals forces increase, ionic bonds multiplication, electronegative bon attraction (H bonds, etc.)) can be quite impressive. Into your specific case compare detonic paramerters of PVN, VN (or equivalently ethyl nitrate) and 1,3-butane diol dinitrate you will be convinced (I did this kind of studies on many families of compounds; actually everytime I was able to do so). You of course know that density is one of the heavier influencer into detonic parameters; it plays a role onto VOD (velocity of detonation). Increasing the number of monomers increases the molecular Vanderwaals forces, thus the compactness. Into this field you of course know that PVN, just like nitrocellulose of high NO3% (or semtex, or cyclonite plastic) may burn (maybe deflagrate) but that is another story if you put an actuator / detonator into play instead of self-confinement from flame propagation and own weight. B) If you consider impact sensitivity (IS), you will notice that IS goes up while the molecular mass increases (thus the polymeric weight)... this means that the compounds become less sensitive with polymerisation versus monomer. Increasing the molecular lenght increases the (thermal/impact) energy due to inherent dissipations modes. IS (M1) < IS (Mx) < IS (pM) Using a polymer will thus be way safer than using monomers. Again it will usually simply burn, but it may detonate at a much higher velocity rate if in contact with a detonator. PHZ (PHILOU Zrealone from the Science Madness forum and from newsgroups (Alt.Engr. Explosive, Pyrotechnics, Rec. Sci. Chemistry,...)
Usually the density also increases because there is also often phase change that occurs "naturally" due to polymerisation... So a volatile liquid (or a gas) may turn into a liquid, then a wax and finally into a denser solid (not always cristalline but often with cristalline domains; they can be changed with thermal plateaus - or with help of polymerisation catalyst see atactic - syndiotactic and isotactic to get an idea of the influence on polymer parameters) PHZ
The Gayest Person on RU-vid : And YOU mate... WHEN, are you going to resume the thermite experiments.? I fuckin' LOVED what you did.! :) Come on, let's start it allready... Pretty please..
You haven't lived until you have been chased by a tank car (as I was as a late teenager volunteer fire fighter) of 3 beta-2 alpha vinyl butyl acetate... Flash point -38 degrees F, shipped as a gas compressed into liquid. Goes BOOM ( insert quote from the Fifth Element here) if it escapes or if fire/heat impinges on the vapor space at the top of the tank. Known to BLEVE (Boiling Liquid Expanding Vapor Explosion) and the blast wave can wipe out most everything for about 1/2 mile around. So impressive, a chemical company Union Carbide made a safety film on it after a car of it blew up in a rail yard in Houston.
Nobel used to do his experiments in a boat in the middle of a lake...just in case! It also made clearing up easier, it’s only a question of time before you go boom! Very informative until that time though
Years ago I made TATP (couple grams) then added just enough acetone to dissolve it. Then I had the bright idea to put styrofoam till it would not dissolve. Then i let it room dry when the styrofoam turned into a hard plastic I touched it with a lit Punk and omg about blew my hand off. Don't Try Anywhere.
@@diehard7502 hi there ATF/CIA/alphabet soup glow-in-the-dark agency DON'T MAKE TATP. It is that one explosive that's so easy to make that everyone who should not be dealing with explosives can just cook up a too large batch (by that i mean a few gramms) and blow their hand off. It's also stupidly unsafe (sublimates and crystalizes in the threads of a container's lid) so that's at least a self correcting problem. DO NOT MAKE IT. If you can't make something better, you should just stay away from this part of chemistry entirely.
Just a minor correction, polypropylene is not a glass at room temperature, its glass transition is around -10°C It becomes progressively ductile from glass to fusion (150°C), which is why it becomes softer in hot water However, the spoons really are brittle, much more than the PP samples I usually see in the lab, so my guess is those spoons have some additives to make them less flimsy despite being this thin (fatally making them brittle) Edit : The glass transition of Nitrocellulose is around 70°C ( from : Use of DMA-material pocket to determine the glass transition temperature of nitrocellulose blends in film form), the high temperature you evoked is its fusion temperature Glass transition and fusion are two very different things in polymers. They stop having a constant modulus after the transition, but they do not become immediately a paste. In the case of semi-cristalline thermoplastics (yes, some polymers form cristals), they melt abruptly once you reach fusion temperature. Fully amorphous thermoplastics become continuously softer as you increase temperature, without any specific transition, they are just sort of liquid-ish at some point So, to sum this up, it is not exactly the glass transition you are looking for if you want to process the product, but the temperature at which your substance reaches a certain modulus required to squish it well enough
Depending on the grade of PVA, it should be water soluble to various %, but it takes a while and you have to heat the crap out of it (80*C). However, once you have it in solution, you can crash it out with alcohol, acetone, ethyl acetate or what not; this will make very fine powder ;)
Not so fun fact: between the early 1890's and the early 1950's, motion picture film used nitrocellulose as a film base. If you think that's a bad idea, yes, you're right. It has caused on multiple occasions fires in both projection rooms and film vaults, if you don't store it well, it decomposes into an aweful tar and extremely flammable gas. Nitrate film has caused the loss of countless motion picture media and a few death. Also, there's about a windows of time of about a decade where you could have used radioactive lenses in conjunction with nitrate film.
The syringed polymer was impressive from a practical point. not a chemist but i would try packing the powder down, like a black powder banger. Could the polymer powder work the same way? Stick it in a wee cardboard tube and find out! 👍👍 Love the channel! Subscribed & liked
I used to have to make large quantities of PVA solution for an after school science enrichment program... it is a *_massive_* pain to get into solution requiring far too much time in front of the hot plate with an electric mixer. Once I made it tho, add a Borax solution to make slime !!
I'm a master finisher was 40 years of experience . You want to blow up using polymers then go to vapors form with lots of particulate with no airflow , spark BBOOOOOMMMMM ! Non-dairy creamer explodes real well also .
i think the real lesson to be learned here is to keep your open reaction vessels in the main shot so that when you accidentally do something horrible to them at least you'll get some Content out of it
If we can figure that out the opportunity for 3d printable solid rocket boosters would be incredible! With the right design geometry/thermal management and scaffolding something like that could decrease the cost of a space launch to raw materials + what ammounts to injection molding 2.0! Thats awesome!
compressed charges are "ok" in firearms...... (sorta.... usually its a sign of an overcharge) compressed charges in chemistry and boom booms...... BAD!!!
Nitrating pyrrol would be more of a challenge (it´s more sensitive, has more groups to nitrate, would be the better explosive, but is apparently a bitch to work with so that no-one ever seriously used it)
Definitely the best person to teach kids chemistry, how many kids are going to come home going, I wasn’t paying attention so he lobbed a piece of explosive putty at me?….. None…. The fine mist will keep the others in line…. But mostly they’ll all be cramming to see.
