Hello, everyone! I bought HEPTYL - The Most Dangerous Substance!? You will be surprised to see the title of a video. But I will prove in this video that HEPTYL is the most dangerous substance in the world. While reading the latest news, I noticed that many companies are starting to make more efficient and cheaper space rockets, some of them can even return to the ground and deliver cargo to orbit for less than 100 dollars per kilogram. Surprised?
Attention! This video shows dangerous experiments! Do not repeat the experiments shown in this video! - วิทยาศาสตร์และเทคโนโลยี
Bruh the one person in the comments who told Thoisoi to change his voice was really ridiculous. Don't listen to him Thoisoi, you have an amazing voice. Everyone misses it.
Agree! He has a very manly deep voice. 👌💯
Me 2❤
It wasn't his voice but I agree I miss the old one.
Definitely agree.
He said in a post that he got someone else to do it because of burnout. I don't think he is uncomfortable with his voice, I just think it is hard.
We want to hear YOUR voice again.
It's really odd when it cuts to him talking while being dubbed over.
yes, you DO NOT have to PAY SOMEONE to do a voice over.. we KNOW money is a BIG ISSUE for the vchannel right now... so LISTEN TO YOUR AUDIENCE and STICK WITH YOUR VOICE until you can get back to doing science.....
YEAH! Heard him telling "such metals" used to be nice! 😅
Yep, his English was fine!
Yeah, I love the personal touch it gives!
dont get me wrong, the new voice is good and professional, but i miss the old russian english voice
Engrus language 🤣
Chinglish language is also amusing 😉
Russian accent is probably banned on TH-cam nowadays.
Estonian
+
Not as professional in content awareness
I miss the old voice acting tbh. Still great content
Agreed on both
Yeah when he said vicious liquid, instead of viscous liquid, I died a little inside lol.
I wonder why the views on the english channel are way lower than the other channel. There are plenty of people on both languages and arguably way more on english since that is the language many countries learn as the second language.
NileRed is way lower quality compared to thoisoi yet he get's a lot more views while doing useless non-educational content.
Thoisoi deserves a lot more recognition, he earns it, his quality is just awesome.
I can’t make it through a video with this new voice overdub. 😢
@@Splarkszter Because TH-cam isn't about who makes the more educational content. Consider the fact that Mr Beast has the #1 channel on TH-cam for a moment. When a channel with informative and technical content succeeds, that's an outlier. Plus, Thoisoi being at nearly a million subs on his English channel is still pretty impressive for a channel focused on educational chemistry content.
I wanna hear your old voice again :(
What is this guy thinking? I miss his awesome European accent.
The whole time, I was thinking all of the splattering and spilling seemed a bit dangerous. Sorry to hear about your lab, but thanks for sharing your cautionary tale.
he used hydrazine in a diy fume hood... lined with paper... without buckets of extinguisher outside... in a room full of hydrazine-flammable items... and the room was made out of hydrazine-flammable material... this is *not* a cautionary tale, it's a massive self-own even after the fact
one thing i notice to him is his native, Heavy and Thick Russian-English accent... he may be sounds professional and improved because he embraces dubbed contents... i miss his own voice to be used on every videos he made because it sounds like he put more effort on his contents and topics
He’s Estonian
The passion in the voice is the thing i cant hear from the new voiceover
@@wrs900 - yeah, he’s got a lot of passion. He speaks articulately but it’s just a thick accent.
He’s a weird guy, every video he gets 2000 comments that say use your own voice, but he still won’t change and go back to his own voice .
He must really hate his own voice if you won’t use it when every single person who watches this video says, “use your own voice”
@@wrs900 this is what happens to some audiences who wants to make a change or dictates the content provider... i don't know if Thoisoi made a mistake of listening to KARENS than majority subscribers who enjoys his accented English and wanted to keep his natural voice
Plus at least 1 auto-dubbing mistake: 'viscous' 'vicious'!
Sorry for what you had to go through, it’s incredible that you managed to make a great video out of that nonetheless, you’re one of the best on TH-cam thanks man !
"Do not ask where I bought it."
I'm gonna make a wild guess...
Figma Baldrich
Ligma baldrich
Sigma Baldrich
I'm guessing it did not come directly from Sigma.

What happened to your voice, sir
puberty kicked in.
Not enough vodka, to much Tennessee Whiskey.
Next time you want to make the freezing mixture or "cold bath" with ethanol and dry ice, you might want to try reversing the order of addition: Start with a beaker with chunks of dry ice in it, and then slowly dribble ethanol into it. The same sublimation and dissolving process will happen, but with less liquid in there to begin with, it should be less violent and not splash the ethanol around as much. Also, once you have filled it to the volume you need, there should still be some solid dry ice left, so the solution will be saturated. In which case the temperature reached will be a lot colder - a saturated solution of dry ice in ethanol should get to more like -80 degrees C. If you keep it in a saturated state by ensuring there is always some solid dry ice immersed in the ethanol, then it will remain at that temperature. Much like how a mixture of water ice and liquid water stays at (or very close to) freezing point and won't increase in temperature until all the ice has melted.
I was going to say exactly that. It’s how I do it every time and never had a problem.
Additionaly put the ethanol before in a freezer to save a lot off time and dry ice.
Pounding on table chanting "OLD VOICE, OLD VOICE, OLD VOICE"
The guy said "viscious" instead of "viscous". -one more reason for Thoisoi to bring his own voice back...
I know your a bit burnt-out with the stress lately, but we'll be glad to hear you again 👍
lol I was wondering about that but honestly when youre talking about these kinds of chemicals and mixtures "vicious" could be fitting 😅 but yea it was probably a misread
Most people: It’s science. We don’t care who narrates. 🤷♂️
Your subscribers: We do…. 🖐️🥺
I'm sorry, bro, but I just can't bring myself to watch your videos anymore without your voice.
You used to be my idol😂 but without your voice, it's just not the same😓
Hi, man, sorry but statistics shows that professional voice over is better. And also this saves a lot of time for me to make a better videos and spend time with family.
@@Thoisoi2Perhaps the statistics show better results for the 'professional voice over' however perhaps that is for a different audience. I, and as i read the comments many other vieuwers' like more your authentic voice.
For me the 'professional voice over' gives more the feeling of an irritating american advertisement than something nice an informative that i enjoy.
You make great videos with interesting content however for me the quality is a lot less with this voiceover.
@@Thoisoi2 but your voice is more attractive
@@JanJeronimusYes, different audience. It became less "amateur chemistry" (e.g. NurdRage, Cody's Lab) and more "popular science" (e.g. Veritasium, Thoughty2). It's perfectly okay, just no longer for me.
Statistics for people that haven’t been long time fan’s perhaps. I get it, you gotta pay the bills with views but alienating your existing audience can only bring misfortune.
Damn, I'm glad you're OK, sorry to hear about your lab. :(
So glad to see you still uploading after your recent...setback... hope you manage to keep this boat floating. And for the record, your own voice was perfect
I miss your real voice Thoisoi2! It's part of the reason I like your videos so much. It's so damn authentic :)
I agree, been watching this channel for a long time and your voice is what makes it unique, dont do ai generated stuff or auto voice overs. Stick to your original style and stay unique!
The one person who said to change your voice was wrong. I can't finish the video as it's like watching another channel altogether :/
Every new video u will see:
I miss the old voice 😂
When I was a lot younger, the first science fair in my school came with the ideia that, alongside with shows and demonstrations from the nature sciences themselves, they decided to open a space for a "rocketing hight-fly competition"... my group entered the wave, and I was responsable for both projecting the rocket model and to take care of the fuel that would be used (since the competition stablished only that "would win the rocket that gets higher", and not about how or with what the rocket would be made) and, as a lover of the history of the space race, I researched for a few days just to find that rockets like Volstok I (If I'm not mistaken) or Saturn V were based at the mixture of these two bad boys at the end of the video and... I, as a 14 year-old tryied to went out in the search of the "unsimmetrical dimethyl hidrazin" by myself in the internet and chemical stores.... hopefully the fair was canceled toghether with the rocketing competition, since I asked for a teacher of mine that (I imagine that without knowing much about the chemical itself), after had heard my story about the liquid propelent, to help me obtain it, with the now scary fact that he really tryied to help me buy the thigamajig in professional chemical stores (aparently, he had taken that seriously)... Thanks Thoisoi for explaning and demonstrating the why the cancelment of this fair was probably one of the best things that could happen to me! (also... I loved the way you talked in the videos prior to the use of software so... please, give us your voice back!)
The Saturn V used liquid oxygen/kerosene in the first stage and liquid oxygen/liquid hydrogen in the upper stages. The R-7 family uses liquid oxygen and kerosene. Titan II used hypergolic propellants, though, as did the Apollo spacecraft themselves (CSM service propulsion system and LM ascent/descent engines).
@@ErickC woah! Well, I didn't imagined that existed effectively such large engines with such cryogenic/demi-cryogenic fuels... thanks for the enlightment! (I did never cought a reference to study the rockets themselves, as well as these particularities, since the only thing I had focus in that period was the proper history of rocketirig and the space race, with the remarkable launches and everything, still, thanks for the addition!)
The voice over is not cool.
Thoisoi I love your accent and your voiceovers and I just wanna hear the familiarity that it brings
Dont wanna be offensive here, but the voice and how enthusiastic it is does not match you or the pace of the channel, really starting to put me off watching.
Where is my comrade?
1. Welcome back, I'm glad your back
2. We miss your voice!
-The Challenger space shuttle accident was caused by leaking gasses due to a cold "O" ring that allowed the external tank to fail due to overpressure. There was no actual "explosion", other than the tank failing and releasing all the hydrogen and oxygen at pretty much the same time. That blew the orbiter apart, and the astronauts were alive but probably unconscious when the front of the orbiter hit the water at high speed. They died of multiple blunt trauma, much like people in car accidents.
AFAIK they are still alive....
how? you tell me? but there are pictures of people.with same names that look allmost tje same...but older
@@Lipi19821 They are not alive. Source: me, from watching the news.
@@Lipi19821You gotta have brain damage to believe that conspiracy lol.
@@Lipi19821 Let me guess: Newsmax or One America News...
Which brand of tinfoil do you find most effective?
@@acmhfmggru Yes, I watched it on the news, in 1986.
Crazy. I’m glad you weren’t injured in the fire! Great video as always, but please go back to the old voice narration!
The voice...
Just glad you did not get seriously injured in that fire or have any serious health complications from exposure to hazardous materials. Please be safe. Hope your channel continues to thrive and thank you for all the wonderful content.
homie I would love to hear to your voice, as someone from the internet I don't mind accents from across the world. Do what you want, but don't feel pressured like that. Wish you the best.
Oh man! Did you hurt your throat?! Your voice sounds odd. I hope you heal up so we can hear YOUR voice!
Voice back please!… 😢
Awsome video as always! I wish you the best luck to get finance in order to build a new lab, you definitely deserve it! It's really sad and painful to see our stuff taken by fire or similar event... But the most important thing is that you are alive and well, and you should be happy and glad for it! :)
Glad you weren’t injured by the fire. Take care.
Thanks for this video it was very informative, useful and interesting at the same time, now I feel like innovator, researcher and scientist, kudos
“Don’t ask me where I bought it”
*Literally holding the bottle which says where he bought it*
that's the manufacturer label, not the distributor necessarily
@@constantinf.5764 Still, with a quick Google search, you can easily find who resell those chemicals.
And yeah, I wouldn't mess with UDMH. It's literally Hyde of the rocket fuel which is apparently why no one in rocketry industry but chemists use it anymore.
Remember a while back there was also a narrator and everybody wanted your voice back. It’s the same now. The accent is part of this channel.
I’m glad to see you’re making content! I hope the lab rebuilding is coming along.
i miss your channel ever since you changed the voice over.. when things like this happen i tend to not watch a video. im sorry.
You sound different.
You can use the kno3 sugar/xylatol as a pyrotecnic gunpowder substitute. Just add a few percent sulfur and a couple percent iron oxide to it and screen it to small granules. Mix in rubber powder and it will make a pretty potent black smoke mixture as well.
You don't need a new voice, your old voice is amazing!
Please narrate with *YOUR* great eastern European accent.
We want his original voice!
I understand hiring a VA, but your voice is very nice and the accent is fun to hear, plus it delivers emotion and emphasis no VA can :)
Thoisoi you have an amazing voice. Everyone misses it.
The channel’s soul is gone without your voice 😢
Men, you don't make videos, you make art and record it. Congratulations! Hugs from Brazil 🇧🇷
@5:50 The Shuttle SRBs were destroyed ("exploded") by the Flight Termination System. They did not explode "on their own" due to some failure. What actually caused the the destruction of the STS, was burn-through from one of the SRBs, into the main propellant tanks -- which in turn caused structural failure of the entire STS as a system. The release of a huge amount of liquid oxygen & hydrogen ignited to conflagration, rather than detonation. It was drastic aerodynamic changes, that the Shuttle was not designed to withstand, which destroyed the vehicle. The rather macabre evidence for this fact, is that the Shuttle crew managed to change a number of flight parameters & electronic switches/settings *after* the disintegration of the Shuttle; some of the crew may have been alive for some time while tumbling back down towards the ocean; brain function likely ceased long before impact.
I love your videos with your original voice. This video just threw me off. Hearing your voice made things more understanding to me. It is like a friend teaching me something.
Good video but doesnt feel right watching this with the new voice.
This voice actor is incredibly good. You might want to add a note both at the beginning of the video and description, or come on and speak with your voice heart to heart with the community about the change. They will be more supportive. Some people said you mentioned somewhere about burnout some people say something else, so it would help if you explain to them. If you changed voice because someone complained ignore them your voice is fine. If it’s from burnout this VA is very good, ty for finding a way to keep bringing us content, you guys will work it out and get it polished up. People were caught off guard with the change so they get a little emotional and post some charged up comments. ❤
the videos are so much more understandable with the new voice, i have an accent myself aswell so i understand how frustrating it can be but you make great content man
Glad to see you're posting new videos. Hope all is well after the incident.
I thought that was chlorine triflouride.
FOOF
FOOF
Please stop using the narrator! We miss your wonderful voice 😢
After overcoming the shock of the new voice and watching the video I did find it easier to understand but you have a decent fan base, you shouldn't feel like you should change anything.
it was an interesting video I liked hearing about the small history of Russia space program in relation to different fuel types they played around with
Lab flames have a habit of spreading - hope you get your lab back together soon.
I had an ether fire in my fume hood (yes, I was using a flame-proof ceramic heater) and I didn't notice it until all the hairs on my arms started vapourising. The real fun started when I tried to smother the fire with a fire blanket and ended up wafting burning ether onto the floor - I didn't know I had done this, though, until my lab partners started jumping around with their legs on fire. By this point, the ether burned out, and I was super grateful I had remembered to put the lid on the winchester of ether.
Also, even NASA have done dumb things with UDMH - llis.nasa.gov/lesson/2196
As for that MythBusters episode with the salami as fuel...If they had a more concentrated heat source with a better way of directing that heat to a concentrated flame...and had a way to semi heat that Salami so the oils would produce gasses, I think they might have succeeded.
I thought they needed to meter out the nitrous more slowly since it exploded any time the salami actually ignited. Fortunately, they are too smart to listen to me😉
please bring your voice back dude it was way better
Dude!! caught your lab on fire!! you get an upvote, I subbed a long time ago.
Please go back to YOUR voice!
old voice please... thank you
thanks for sharing, I'm glad no one got hurt and hope you keep at it.
Thoisoi we miss that voice brother. It made the videos 10x more scientific.
17:43 Lol you bought it from Sigma-Aldritch. Can still see the label clear as day. Not hard to find the stuff just sorta google their site and search it up.
The hard part is affording it. Sigma is quite proud of their chemicals. I was on there looking at their prices for castor oil, nitromethane, and methanol for purposes of brewing up my own model engine fuel and found that I'd end up making my own fuel for about 50-60 bucks a gallon whereas my hobby shop sells pre-mixed ready to use high quality fuel for 30 bucks a gallon 🤣🤣
Good luck ordering from Ligma Baldridge unless you're a business that deals with such things, school or governmental body of some kind.
Don't be nuisance
Didn’t his lab burn down recently? And this is what he’s doing now? 😂
Ah, I see. This is the “before” video
Yup.
I sent $50 hoping we would get more content, sooner.
Sadly the crappy synth voice is back too
collaboration with NileRed sounds like a cool idea
this is so sad that you felt enough pressure that you needed to hire a voice actor, we love your voice and i definitely miss it. thank you for all of the work that you do man
I sincerely love your channel and I sincerely say I cannot & will not listen to this AI voice. This is not you :(
Bro were is your voice? That AI garbage is really distracting.
This channel is pure gold lmao
Your unique and beautiful voice helped me to keep my attention to your videos. Now, I am not as interested in learning about chemistry
Nah bro I unsubscribe 😢
Please go back to using your own voice. Your voice is so much better.
This was such a fun video. Its not everyday he does something i actually understand.
5:01 As a kid with my friends I used to tape those engines to a bamboo skewer and launch them that way lol. It's pretty amazing actually. I had the idea to make it so when the end blows out(for the parachute) it would ignite something but don't remember if I ever tried anything.
This voice over sucks. Where is the OG voice?
I'm sorry, the synthetic voiceover triggers my misphonia and makes this almost unwatchable for me.
Maxim, please send notice if you ever return to using your real voice and i will come back to this fabulous channel.
✌️
Respect for handeling both substances
This is the first video of yours i see, and i like it!
I'd agree with the many others who prefer to hear your voice over a narrator. My reason is that as someone who learned enlish later in life, i like to watch people while they speak, so i understand better. It is a bit confusing to me that the lip movements aren't really synchronous with the voice i hear. Even though the narrator does a good job and is easy to understand.
Please, for the love of god, stop dubbing your videos. We want to hear your voice, not someone elses.
Please go back to your old voice. It's not funny anymore.
Excellent science. You are having too much fun. Keep it up! I love it.
Lol when i was about to miss old voice, i read the comments.. Great content i love your work, with regards!
You clearly don't read the comments on your video's, we don't like the Robo voice.
I don't like the voice over!!! Let's go back to using your voice!!!
I've never watched your channel before.
I agree with everyone else here, your voice is what we want.
Maybe you can make a fire extinguisher? Not a joke (maybe a little) I think the science behind them would be something cool to show.
Woke up to see you in my notification bell. Going to be a great day your video is awesome.
Modern APCP motors typically use HTPB or PBAN as a binder.
Silicones are typically used to inhibit the outside and between grains in stacked instead of monolithic cast-in-place motors.
🔊Well, let me interpret the meaning of "heptyl": You see, "hep" means liver, and "tyl" means flying dinosaur. This chemical was expressly formulated to exterminate pterodactyls in the case of a "Jurassic Park" type event....
You panicked, the worst enemy to deal with a fire. With the bottle of heptyl near the flamme source, I can't imagine the disaster...😢
One interesting thing that you didn't mention (I guess, with your lab being on fire, you had other things on your mind) is that the Apollo lunar module used nitrogen tetroxide and UMDH (I have no idea why it's sometimes called "heptyl" because, AFAICT, it doesn't contain seven of anything) as propellants, because they wanted the simplest possible system for landing on and taking off from the Moon. The fuel and oxidiser tanks were pressurised with helium gas so that the engines didn't need a turbopump, further reducing possible points of failure.
Of course, the upshot of using these substances is that the engines corrode quite quickly. As far as I'm aware, the only times the descent or ascent engines were fired more than once were during Apollo 13, where the descent engine was used twice in place of the SPS, and Apollo 9, which was a thorough test of all the LM's systems in low-earth orbit.
Wow, kazow. Very sorry to learn of the lab fire.
Best wishes for a quick rebuild.
We love the charm of your Estonian voice. Be yourself, Maxim. We appreciate your work very much.
BTW: The shirt is greatl I didn't miss the pun.
Just glad you came out okay after the fire!
bro, i loved the way you talked, the accent, it was original, it was you!
very cool, fun with chemisty. thank you
