With magnesium silicide/silane, it's more fun (imo) to use water to get the product. You can break the test tube containing the Mg2Si and drop the solid chunks into water. They react to form bubbles of SiH4, which then burst into flame when they pop on the surface. If it doesn't want to make nice bubbles you can add a little bit of soap. It's a lot more controlled than adding acid, so you get to see the reaction more clearly and it goes several times. As a fun side effect, you can actually see the SiO2 (sand) that is the other product of the combustion as it forms on the surface of the water.
This is why chemistry is so magical; you literally just created a "fire potion" like some kind of STEM wizard. Quick question though, at 4:03 you mention diborane having a weird Swedish odor. I've never actually been to Sweden so I don't what it smells like there, but would Swedish fish odor be comparable in scent?
Lol, I'm never gonna hear the end of that mispronunciation. I don't recall smelling the SWEETish odor myself, but I don't think it's comparable to fish of fish-shaped candy.
You should consider making silver plating solution! It’s very hard to get hold of for electroplating hobbyists, but it’s definitely something you could synthesize to make it more accessible.
Yay I used all 3 of these plus arsane stannane trimethyl aluminum and more to make lasing chips for Boston Lasers in the early 2000s. One happy accident is the valve that added the trimethyl aluminum fired a couple extra shots in the chamber and we rolled with it. The result was 614nm orange laser chips with a safe operating power of 250mW.
I love that you're doing that over a sanitary sewer manhole cover. I'm not going to say it's not safe, I'm not an expert on that kind of thing. I will say I'm honestly disappointed you didn't manage to launch it into the sky...
Hello good sir. This is a really interesting video. You are my favourite RUclips chemistry channel. You do cool stuff. And your voice is comforting for some reason lol
it would be great if you didn't start with obvious precursors, like borohydride. I want to see it starting from boron trioxide, phosphates, and silicates.
I suppose I could superheat calcium phosphate with charcoal in a kiln to get the phosphorus needed to make phosphine, but making silane from silicates wouldn't make much sense, since silicon dioxide (sand) is fair more abundant. Likewise, I could make the sodium borohydride myself from boron trioxide, but that would require access to sodium hydride and methanol, so ultimately, buying sodium borohydride directly makes the most sense.
@@LabCoatz_Science Boron trioxide and magnesium metal to magnesium diboride. Displacement of the diboride produces boranes. And yes, I misspoke about the silicates. Sand makes much more sense.
@@cooldude7301 Honestly nothing, it just depends on if you have better access to borohydride or magnesium powder. For me, borohydride is more available.
one of the best ways for some crazy chemistry demonstrations for bored chemists (+students that searching an inspiration lol '~') Keep your cool channel up 😃
You're one hell of a fucking badass you know that? I've never seen anyone pour a whole beaker of concentrated sulfuric acid in and around his RBF with such grace!🤣
Can you make a video purging the tubes with insert gas and putting a balloon over them before producing the gas. Maybe magnets or something. Then pop the balloon
While some people prepare for the zombie apocalypse by loading up on guns and what not, I'd much rather stick with chemists and makers who can make dangerous and flammable things out of stuff they find. Or high voltage things. Bullets will eventually run out, but if you have the know how, you can always scrounge up stuff to make weapons for hunting and defense, lol. Joking aside, very cool!
I'm not sure I understand the question...are you talking about putting diborane in a rocket engine? If so, it really wouldn't be a good fuel (probably why NASA rejected it), but if you want ideas, look into how they do stuff like that in hypergolic rockets.
Yeah, or play with hyper-toxic self-igniting substances. The only extra thing needed is a little spice of radioactivity such as Cs-137 and I-131. UPDATE: now when you also demonstrated that the reactions are way worse than playing with fire, namely explosive, what is the purpose?
Most of these gases do find some uses (silane in the semiconductor industry, phosphine as an animal poison, etc), but uses involving their pyrophoric properties are limited. NASA uses stuff like diborane to ignite their rocket engines during takeoff, but besides that there isn't much...might be cool to use in a weapon though!
So wait, the smoke from the silane is silicon dioxide? The smoke is sand particles? If I'm not misunderstanding you, that sounds very dangerous to breathe in.
Red phosporous eh? Thanks for the heads up, that is an, um, useful reagent for, um, legitimate home chemistry, does he carry iodine crystals or some other halogen source too? Um, reasons..
Yep, diborane's been tested as a rocket fuel, but ended up a) being too unstable and b) producing boron monoxide during incomplete combustion making it not super viable
It's just a storm drain. I use it for most of my dangerous experiments, because it happens to be in my backyard, it's decently far from the house, and if a tiny amount of something spills (like the HCl in this video, when I jerked back from the silane), I can just rinse it away.
I hope to do arsine sometime (once I can safely deal with arsenic vapor, lol), but alane isn't a pyrophoric gas: it's just a highly flammable non-volatile solid. Still might be fun to try though!
I've considered doing so. It's possible to bubble the gases through water and into an inverted flask (phosphine would be best for this, since silane and diborane both react with water to varying degrees).
Not you im concerned with its people thinking It's something they should try.if there looking for help to do it on youtube they shouldn't attempt it A kid in Sweden killed himself years ago doing just this

i was exactly gonna comment the same thing, i know you meant to say sweet-ish but it sounded like swedish
You may be my new favorite RUclipsr, well you and explosions and fire of course
4:30 I have never seen diborane ignite like that before! That's so cool! Good job :D

Thank you very much, I appreciate the complement! Hopefully I can continue to entertain great people like you!
The diborane was so cool, every one of the shots was amazing.
Man that borane reaction was so aggressive.great video as usual.keep up the great work
Don't ever came into the pressure to take these videos down. In fact have a backup them somewhere and include that link in the description

I'm not even a Swede but even *_I_* find that offensive!
😏😊
I once dropped Calcium Phosphide into water, each bubble of gas ignited at the surface and made a cool smoke ring

How could you make diborane without letting the reactant go through a ceramic rocket nozzle

On top of the storm drain?
Better living through chemistry.
Yay Labcoatz!
The small scale borane reactions looked nicer
“Diborane has a weird Swedish odor…”
“Whåt?”
I'll never hear the end of that mispronunciation, lol...
@@LabCoatz_Science dude no worries, I’m still giggling about it 6 hours later. 😆 made my morning.
Imagine having these gases liquefied under pressure in glass ampoules, you would essentially have enslaved fireballs lol.
Don't think for a moment that I haven't already dreamed of doing that, lol. Maybe one day, if I can get ahold of liquid nitrogen!
@@LabCoatz_Science Oh boy, that will be fun!
Yeah, or play with hyper-toxic self-igniting substances. The only extra thing needed is a little spice of radioactivity such as Cs-137 and I-131. UPDATE: now when you also demonstrated that the reactions are way worse than playing with fire, namely explosive, what is the purpose?
I had no purpose, I just wanted to experience working with them firsthand, like I did with thioacetone, selenoacetone, and resiniferatoxin!
Quality safe experiments can be found here!
The question is there a way to harness these reactions for things?
Most of these gases do find some uses (silane in the semiconductor industry, phosphine as an animal poison, etc), but uses involving their pyrophoric properties are limited. NASA uses stuff like diborane to ignite their rocket engines during takeoff, but besides that there isn't much...might be cool to use in a weapon though!

Yep, and you're right: it's not the best stuff to breath in. It's not a death sentence by any means, but it's not advisable.
4:02 "Toxic like phosphine and has a weird swedish odor."
Toxic gases that burst into flames when they contact air? Sounds like a guy I used to know. How long have you known Andy?
Mad scientist
Thank god you're doing this on top of a well. Who knows what would happen if these chemicals were released into the grasslands :P

wonder if NASA ever considered it

What is underneath that giant metal manhole cover you're doing the experiments on lol?
It's just a storm drain. I use it for most of my dangerous experiments, because it happens to be in my backyard, it's decently far from the house, and if a tiny amount of something spills (like the HCl in this video, when I jerked back from the silane), I can just rinse it away.
It's the drinking water supply for the city he lives in.
Playing with phosphine? Seriously?
noice! 😍
Hyyyypppppppeeeeeee!!!!!!!
Cool but but what about alane and arsine which are also pyrophoric
I hope to do arsine sometime (once I can safely deal with arsenic vapor, lol), but alane isn't a pyrophoric gas: it's just a highly flammable non-volatile solid. Still might be fun to try though!
@@LabCoatz_Science Volatile organoarsenic compounds are rumored to be one of the worst smelling chemicals like Me3As
How feasible would it be to collect these gases air-free so you could actually isolate them?
I've considered doing so. It's possible to bubble the gases through water and into an inverted flask (phosphine would be best for this, since silane and diborane both react with water to varying degrees).
Silan react with water extremely fast, with water fumes too
You ever look into Greek fire?
I've heard of it, but I've never looked into it. Maybe I will!
I can see why they considered diborane as rocket fuel
@4:03 has a weird Swedish odor 💀
