It's got hardware, dinner party and fireplace ingredients. It's gotta be the hardest damn thing to clean up before you even start the reaction. What's not to like?!?
Ah yes, as expertly demonstrated in the reaction of Al and S (w/ steel wool), a timber shed with lots of dry wood makes a good location for conducting exothermic reactions.
I love old chemistry papers, since they often used chemicals really easy to get hold of (considering it might have been the best they could do at the time) and the process ends up being pretty manageable for modern Australians in sheds to do
I remember taking a safety course (H2S alive) for working in the oil field. Apparently one of the scary things about H2S is that if you get exposed to a lethal dose (even without a knockdown), it might not kill you right away. So you may think you're fine, but it can build up in your system because it'll dissolve in your blood and then later that night or the next day your lungs start to fill with fluids and shut down due to damage from the gas, and that's what will kill you. Really nasty stuff, the instructor who was teaching this stuff was very adamant that there was no "safe" exposure limit to H2S despite different regions having "safe exposure levels". His argument was that you take a look at the regions that have oil and gas industries, vs the regions that don't, and the regions that have these industries "for some reason" have a higher safe exposure limit than regions without this industry.
If you calculate the H2S content you need and only put in enough sulphur for three or four equivalents, you can add an excess of wax to make the cleanup easier. Once your reaction is done, just heat to the melting point of the wax and then pour the rest of the wax out. You can reuse the wax if you really want to, as long as you don't use a literal burnt stick for a nucleation site lol. Should also stop the sulphur fouling your precious precious Claisen Adapter (and everything else).
After watching like 50 of your videos I finally have a useful suggestion: Don't use candles as your paraffin source. There are weird (cheap) formulations used in candles that often contain residues of all sorts of things including perfumes used in the same molds. Just buy a block of canning wax to be sure you have purity. It's cheap.
"12 grams candle" in a scientific protocol would get the fuck out of my attention. I'd probably try a "12 grams candle" experiment before any of those fancy "12 grams petroleum-based high melting point mineral wax (CAS number, company/supplier)" type protocols
Finally, you're making something I know what it is! Known to laymen as sour gas. I took a safety course for working around it (oilfield work) and they told us "if you can't smell it, it's either not there, or you're already dead." Fun!

The bacteria in the skimmer started churning it out one day and when I took the lid off to figure out what was making the smell- blam, the whole house smelled like rotten eggs.

Here in Germany you can actually buy pre-made pellets that you can heat and generate H2S. They are called "Sulfidogen". They can be easily homemade: 25 parts by weight of paraffin oil are mixed with 15 parts of sulfur, then it is melted on the water bath. 7 parts of kieselguhr (very fine SiO2 basically, the same you can use for filtering, then its called "Diatomaceous earth" I think) are stirred into the homogeneous melt. The mass is brittle at room temperature, but plastically deformable at approx. 40 ° C. Small portions can be pierced with the cork drill. This might be cleaner to work with and make less problems. Also, maybe less heat is required as they use already liquid oil instead of wax.

“12 grams candle” was way funnier than it should’ve been. And yeah I’d stick with argon for the next run if it’s not too much of a pain. You’re likely right, with enough air you’re below the flammability threshold, but why risk it and/or rely on your small air pump and hope you’re below the threshold of your air/HS glass shrapnel bomb detonating

I come from the area of Texas where roughly all of the crude refining and chemical production was done. Exxon, Shell, Dow and Co. There are actual air raid sirens scattered about to alert the surrounding cities to various refinery disasters…“unscheduled gas vents” and “some of your parents blew up” etc etc etc. They test them weekly on Thursdays. Always a big hit with the dogs. H2S smells just mfn awful and it’s everywhere. It goes from a bad fart to completely overwhelming and then yea…when you can’t smell it anymore you done messed up. Headaches and nausea and such.
regarding cleaning the flask: at uni when I made sulfur chlorides once, I used salt in ethanol as an abrasive to get most of the yucky residue out. fill it in, stopper, shake the hell out of it. got the idea from an online guide on how to clean tarred up bongs. ;)
Actually levels as low as 15ppm of H2S is dangerous (provided you are in the area of H2S for a long period of time). We learn this in our H2S Alive course for the oil patch.
The Aphex Twin soundtrack is so perfect for your videos. I love how the bit at 9 minutes is a completely frayed and decayed continuation of the earlier bit. The music adds so much to your production value!
I used H2S liquid as a sulfur donator when I was growing MoS2 on Graphene (i also grew the graphene and transferred it onto silicon wafers) because the ATTM (Ammonium tetrathiomolybdate) reaction sometimes wouldn't happen. I used a PARR vessel to create high pressure temperatures which drove the reaction. The whole goal was to show that if the MoS2 seeded properly and grew on the graphene, the graphene could serve as the electron transport layer in a Hydrogen Evolution Reaction. which it did. Point being, H2S is the most putrid rotten egg smell i have ever had the pleasure to work with. I did notice that in one of the shots of your reaction there were distinctly large "bubbles" of gas forming, but i think the surface tension of the molten liquid was very strong and trapped it. The clip where you had a burst of gas was when 4 or 5 of those "bubbles" burst open. So i think that you could safely say that this generates a ton of H2S immediately, but because of that surface tension it traps it until there is enough heat to break the tension and then it releases the gas that accumulated over time.
OP I love your Channel. Im interested in science but havent looked up much chemistry on youtube yet. Am from Germany and saw you in my recommendations 1-2 Weeks ago. Am binge watching your vids since, love your unique flavor. A really well done blend of "science/chemistry" and "what people want to see on youtube" for me. Great character and great example of how robust some of the chemical processes are in terms of tolerance, which I like very much.
@@xEclipse56x It's a much longer story than can fit into a UA-cam comment... Don't lose sleep over it. Suffice to say I've seen a few "de-evolutions" (one in particular very disturbing) caused by games and detachment... You just happen to have the right wording combo to tap the nail on the way by 🤣
One professor told me safety advice that I carry with me always, and it's somewhat applicable here. The gist was that if you get that feeling coming from your subconscious that you're being unsafe, you should listen to it. Because mammals are well-evolved to develop patterns to predict future survival situations. Considerations to safety and building that survival sense is never a fool's pursuit.
candlemaking dude here - just FYI most candles aren't pure paraffin - they very often have soy and other waxes in them, even coconut oil, to get different properties, strengths, glass adhesion properties, etc. I'm not sure what side reactions this may cause, with all the added amino acids, but just FYI if you do this in the future - it's pretty easy and cheap to just get paraffin from candle suppliers or even camping stores, for waterproofing. it should actually be quite slimy at room temperature... which the "dry" candle tells me there's probably a decent amount of soy additives in that candle.
Wow, that brings back memories. I evacuated our Jr. High School when I was in 8th grade (US) in the '70s, heating paraffin and sulfur in a test tube over a Bunsen burner in the science class. I found the procedure in an old book I bought at a university "get rid of old books" sale. I just wanted to make "smell of rotten eggs" 😬.
Somehow this has been one of your scariest videos lmao. The sudden kind of explosion at 9:26 was something that would have made me shit my pants while in uni. Also 100% agree, using a carrier gas is really nice in a case like this but I would definitely not do it with air again, especially considering that the reaction was kind of a bitch to handle properly. Cheers
This is a very nice method for making H2S, which by the way is a gasotransmitter apparently, like NO. You could make pellets out of wax, sulphur and carbon, maybe a couple of grams each. And melt one pellet at a time when you need H2S. And you can after some tests add different number of pellets depending on how much gas you want to make
If I used H2S more, then you're right I'd probably do this! But knowing me and how much I jumpnaround with projects, I probably won't use it again for another year at least
Nose can get used to low levels too. I was distilling liquids some time ago and it had a slight hydrogen sulfide smell (nothing for me to get worried about, a very slight smell). However, after long time sitting by and taking fractions I got slight sympthoms that turned into light head ache, moved to fresh air and it turned into a large headache followed by dizziness. For large concentration it can make you not smell it almost at all. I'd rate H2S closer to cyanides in danger (I can possibly disable you pretty quickly too). The difference to me is that at least you can smell it unlike CO or if you're like me, HCN at least in slow levels (but yet high enough to give slight dizzyness).
I once singed my eyebrows when I was looking down the barrel of a potato cannon to see if the sparker was working after the cannon failed to dry fire for 5 minutes. Cannot ever be too careful was flammable gasses.
If you want to find out whether the oxygen/H2S mix is dangerous would be to find out the rate at which the H2S is produced, i.e. by measuring the pressure in the reaction setup whilst the rxn is running. With that you could probably calculate some type of steady state concentration based on your carrier gas flow rate. Also, technically, just pumping the carrier gas at ludicrous speeds would give you the lowest concentrations, so you'd probably end up with a safer mixture at higher carrier gas pressures
Oh man, I didn't realize you came back! One of my favorite channels where I have, like, no fucking clue what you're talking about 90% of the time, but I'm enjoying the content all the same
What a weird method for making hydrogen sulfide, really intriguing. I usually make hydrogen sulfide by boiling sulfur and sodium hydroxide followed by acidification with hydrochloric acid, super easy and to my surprise, a very easy cleanup, so long as you use excess sodium hydroxide that is.
Ahh, but his method seems to produce anhydrous Hydrogen Sulfide. That is probably useful in some cases. (I don't know enough chem to even begin guessing if that make a difference).
Thank you for sharing it Tom ! I already knew this methode but never heards about adding charcoal to it. The cleaning kinda traumatised me as it took a entire liter of xylene and maybe 200ml of piranah to fully clean the jar from my side. What i recomment to people using this methode is to just rapidely clean it to remove big junk and keep it as a jar specially for this reaction. Anyway will be very helpful for my 24h bubbling of H2S for making thiobenzophenone ^^
I spent 2 years working on a project that involved condensing H2S into an organic solvent at cryogenic temperatures, followed by a warming ramp to allow it to react gradually. We did tons of process safety work to ensure that the H2S was fully consumed at every point in the warming ramp. Worst case scenario for scale up to a 2000L vessel would have been if the plant forgot to charge the reaction partner to the vessel. Full charge of H2S would have gone in with no reaction, then upon warming it exceeds the solubility limit for H2S in that solvent. We did the math, it would have been enough H2S to evacuate the town should the worst possible branch of the FMEA occur, so we put administrative and engineering controls to make it nigh impossible to occur. Never been so glad to see a project die though, that reaction step always put me on edge.
In the discord, I had theorized that using walnut shell-based sand blasting media could be used to clean glassware. Basically dump some in and shake it up a bunch. Doesn't scratch it, is disposable, still abrasive and is generally quite dry. Could even use it in conjunction *with* water. Figured I'd mention it here just in case it makes a difference and maybe if people agree it'll get noticed? In the states I got like 10 lbs for something like 20 freedom bucks and 10 lbs of dry ass walnut shell is quite a lot more than I realized. edit: Also maybe use a cheese grater for the wax/charcoal next time so you dont end up accidentally pulverizing it lmao.
I think this is a common reaction that should occur with any hydrocarbons, i remember visiting a gas desulfurization unit from a natural gas producer where the molten sulfur had still some methane/ethane mixed in and it produced quite a lot of H2S. Also worth mentionning it also produced a strange mineral they called Carbsulf (not much info about this) which i assume was some kind of carbon polysulfide, it was somewhat translucent and flaky (i still got some in my collection).
Always good to stop and think "How could this experiment have killed me?". It trains your critical thinking and builds up your paranoia levels at the same time!
Yeah, that thing with "maybe i shouldn't use air as a carrier gas in making H2S" got me laughing too.

Headaches and nausea and such.
regarding cleaning the flask: at uni when I made sulfur chlorides once, I used salt in ethanol as an abrasive to get most of the yucky residue out. fill it in, stopper, shake the hell out of it. got the idea from an online guide on how to clean tarred up bongs. ;)
Actually levels as low as 15ppm of H2S is dangerous (provided you are in the area of H2S for a long period of time). We learn this in our H2S Alive course for the oil patch.
Yep, the inside of a woodshed is where I prefer to do my exothermic reactions as well.
Stop misleading the public, i am now confused if I need the blue candle or yellow
The Aphex Twin soundtrack is so perfect for your videos. I love how the bit at 9 minutes is a completely frayed and decayed continuation of the earlier bit. The music adds so much to your production value!
I used H2S liquid as a sulfur donator when I was growing MoS2 on Graphene (i also grew the graphene and transferred it onto silicon wafers) because the ATTM (Ammonium tetrathiomolybdate) reaction sometimes wouldn't happen. I used a PARR vessel to create high pressure temperatures which drove the reaction. The whole goal was to show that if the MoS2 seeded properly and grew on the graphene, the graphene could serve as the electron transport layer in a Hydrogen Evolution Reaction. which it did. Point being, H2S is the most putrid rotten egg smell i have ever had the pleasure to work with.
I did notice that in one of the shots of your reaction there were distinctly large "bubbles" of gas forming, but i think the surface tension of the molten liquid was very strong and trapped it. The clip where you had a burst of gas was when 4 or 5 of those "bubbles" burst open. So i think that you could safely say that this generates a ton of H2S immediately, but because of that surface tension it traps it until there is enough heat to break the tension and then it releases the gas that accumulated over time.
OP I love your Channel.
Im interested in science but havent looked up much chemistry on youtube yet. Am from Germany and saw you in my recommendations 1-2 Weeks ago.
Am binge watching your vids since, love your unique flavor. A really well done blend of "science/chemistry" and "what people want to see on youtube" for me. Great character and great example of how robust some of the chemical processes are in terms of tolerance, which I like very much.
This feels like a Minecraft crafting recipe more than a chemical reaction
The real world called.
@@MadScientist267 Huh?
@@xEclipse56x 🤦♂️ Exactly
@@MadScientist267 I don’t understand why you have a problem with me relating something to a game
@@xEclipse56x It's a much longer story than can fit into a UA-cam comment... Don't lose sleep over it.
Suffice to say I've seen a few "de-evolutions" (one in particular very disturbing) caused by games and detachment... You just happen to have the right wording combo to tap the nail on the way by 🤣
One professor told me safety advice that I carry with me always, and it's somewhat applicable here. The gist was that if you get that feeling coming from your subconscious that you're being unsafe, you should listen to it. Because mammals are well-evolved to develop patterns to predict future survival situations. Considerations to safety and building that survival sense is never a fool's pursuit.
The woodworking version is “If an operation feels unsafe, it probably is.”
Unique reaction! I heard somewhere that a mix of sulfur, carbon, and potassium nitrate in a ratio of 10:15:75 works even better! ;)
candlemaking dude here - just FYI most candles aren't pure paraffin - they very often have soy and other waxes in them, even coconut oil, to get different properties, strengths, glass adhesion properties, etc. I'm not sure what side reactions this may cause, with all the added amino acids, but just FYI if you do this in the future - it's pretty easy and cheap to just get paraffin from candle suppliers or even camping stores, for waterproofing. it should actually be quite slimy at room temperature... which the "dry" candle tells me there's probably a decent amount of soy additives in that candle.
Two videos in like a week!? I love it (but don't burn yourself out!)
It was 10 days ago I think! But yes, I'm just impatient!
@@ExtractionsAndIre I would like to add;
Not only don't burn yourself out, but also don't blow yourself up.
Wow, that brings back memories. I evacuated our Jr. High School when I was in 8th grade (US) in the '70s, heating paraffin and sulfur in a test tube over a Bunsen burner in the science class. I found the procedure in an old book I bought at a university "get rid of old books" sale. I just wanted to make "smell of rotten eggs" 😬.
Lol oops
ah yes. lets have the exothermic reaction take place right next to giant pile of wood.
What could possibly go wrong??
And be in Australia!
I always appreciate the Aphex Twin tracks.👍🏻👍🏻
Somehow this has been one of your scariest videos lmao. The sudden kind of explosion at 9:26 was something that would have made me shit my pants while in uni. Also 100% agree, using a carrier gas is really nice in a case like this but I would definitely not do it with air again, especially considering that the reaction was kind of a bitch to handle properly. Cheers
3:15 classic violent exothermic reaction next to a firewood stack, keep it up
Charcoal, Sulphur, and a candle...
That ain't science, that's witchcraft baby! B)
This is a very nice method for making H2S, which by the way is a gasotransmitter apparently, like NO. You could make pellets out of wax, sulphur and carbon, maybe a couple of grams each. And melt one pellet at a time when you need H2S. And you can after some tests add different number of pellets depending on how much gas you want to make
Instead of cleaning u can jusst name the flask H2S generation flask and use it only for that. No clean up needed. XD
If I used H2S more, then you're right I'd probably do this! But knowing me and how much I jumpnaround with projects, I probably won't use it again for another year at least
really nice of you to show the bong- i mean reaction flask- cleaning. hygiene is important on repeated use of glassware :)
Tom: uploads a video showing a better way to make HS
FBI: 👁️👄👁️
Nose can get used to low levels too. I was distilling liquids some time ago and it had a slight hydrogen sulfide smell (nothing for me to get worried about, a very slight smell). However, after long time sitting by and taking fractions I got slight sympthoms that turned into light head ache, moved to fresh air and it turned into a large headache followed by dizziness. For large concentration it can make you not smell it almost at all.
I'd rate H2S closer to cyanides in danger (I can possibly disable you pretty quickly too). The difference to me is that at least you can smell it unlike CO or if you're like me, HCN at least in slow levels (but yet high enough to give slight dizzyness).
Bit closer to the firewood next time, wouldn't want to be too safe.
I once singed my eyebrows when I was looking down the barrel of a potato cannon to see if the sparker was working after the cannon failed to dry fire for 5 minutes. Cannot ever be too careful was flammable gasses.
thats a really nice saab in the background :D
If you want to find out whether the oxygen/H2S mix is dangerous would be to find out the rate at which the H2S is produced, i.e. by measuring the pressure in the reaction setup whilst the rxn is running.
With that you could probably calculate some type of steady state concentration based on your carrier gas flow rate.
Also, technically, just pumping the carrier gas at ludicrous speeds would give you the lowest concentrations, so you'd probably end up with a safer mixture at higher carrier gas pressures
Extractions&Ire. Give the flask a soak in vinegar for a good hour and come back. The charcoal should readily scrub off.
Oh man, I didn't realize you came back! One of my favorite channels where I have, like, no fucking clue what you're talking about 90% of the time, but I'm enjoying the content all the same
What a weird method for making hydrogen sulfide, really intriguing. I usually make hydrogen sulfide by boiling sulfur and sodium hydroxide followed by acidification with hydrochloric acid, super easy and to my surprise, a very easy cleanup, so long as you use excess sodium hydroxide that is.
Ahh, but his method seems to produce anhydrous Hydrogen Sulfide.
That is probably useful in some cases. (I don't know enough chem to even begin guessing if that make a difference).
@@The_Keeper Yea, I guess but most of the time for me it's not necessary, fair point though
Shoutout for using that nice dry log pile a wind break for generating sulphides @ 3:15
The sign of a true chemist is putting off cleaning the glassware for another day when you don't have any grad students around.
Thank you for sharing it Tom ! I already knew this methode but never heards about adding charcoal to it. The cleaning kinda traumatised me as it took a entire liter of xylene and maybe 200ml of piranah to fully clean the jar from my side. What i recomment to people using this methode is to just rapidely clean it to remove big junk and keep it as a jar specially for this reaction. Anyway will be very helpful for my 24h bubbling of H2S for making thiobenzophenone ^^
It was only yesterday when I learned that farts with a high enough hydrogen sulphide concentration can kill
A big enough fart is lethal.
I spent 2 years working on a project that involved condensing H2S into an organic solvent at cryogenic temperatures, followed by a warming ramp to allow it to react gradually. We did tons of process safety work to ensure that the H2S was fully consumed at every point in the warming ramp. Worst case scenario for scale up to a 2000L vessel would have been if the plant forgot to charge the reaction partner to the vessel. Full charge of H2S would have gone in with no reaction, then upon warming it exceeds the solubility limit for H2S in that solvent.
We did the math, it would have been enough H2S to evacuate the town should the worst possible branch of the FMEA occur, so we put administrative and engineering controls to make it nigh impossible to occur. Never been so glad to see a project die though, that reaction step always put me on edge.
Reminder from the Ruthenium Tetroxide video, you wanted to to a video extracting calcium from bones.
If you don't see Tom upload any more video after fucking around with H2S, you know why
If your chemistry goes yellow, chuck some charcoal in there and you'll be fine
In the discord, I had theorized that using walnut shell-based sand blasting media could be used to clean glassware. Basically dump some in and shake it up a bunch. Doesn't scratch it, is disposable, still abrasive and is generally quite dry. Could even use it in conjunction *with* water. Figured I'd mention it here just in case it makes a difference and maybe if people agree it'll get noticed? In the states I got like 10 lbs for something like 20 freedom bucks and 10 lbs of dry ass walnut shell is quite a lot more than I realized.
edit: Also maybe use a cheese grater for the wax/charcoal next time so you dont end up accidentally pulverizing it lmao.
Favorite Australian chemist on yt
The motto of this channel. "No worries, ah shit." Meant lovingly because you do amazing work sir. I'm not chemist, yet you still make it interesting.
Not gonna lie, I clicked on this video because I thought you were holding an M67 Frag grenade in the thumbnail.
I definitely had a bit of a pucker moment when you talked about running air through that apparatus, so I'm glad you addressed it.
A couple guys on a job at a refinery died to h2s because someone didn't torque a flange properly.
I used to work out on the pipelines of Alberta. H2S was the most common killer. You are a brave man.

I like how Tom turns up the funk in the Aphex Twin when things go astray.
Making the thing I've been taught to fear. Lad.
I think this is a common reaction that should occur with any hydrocarbons, i remember visiting a gas desulfurization unit from a natural gas producer where the molten sulfur had still some methane/ethane mixed in and it produced quite a lot of H2S.
Also worth mentionning it also produced a strange mineral they called Carbsulf (not much info about this) which i assume was some kind of carbon polysulfide, it was somewhat translucent and flaky (i still got some in my collection).
RIP the flask that will never get clean again. 😅
So glad you’re back bro I’ve missed the videos!
