Making test tube liquid rockets 

Hi Cody, I really love your channel. It would be great if you two made a collab.

I blast whenever I can

Yes

please do! ill be waiting ;)

@@halukonal1400 yes!

lmaoooo I wish

Gone wrong OMG 😯😯

"This just in, Montreal is reduced to a smoldering cinder!" "In related news, the United States erects statue observing the first 'NileRed Day,' commemorating Canada's liberation from Montreal.

What? Montreal? Fuck, another RU-vidr I didn't know was Canadian (Probably the closest to me as well since i live in Toronto)

I knew nile was canadian, but not from my area :o

xD I thought that was Nile screaming

That sounds like the sound from a jumpscare. All you need is to put a scary face with the sound

It's having fun almost burning down his building lol

Sounds more like a wow

WOW! Is what I heard

Well now he knows it'll blow up in his face, instead of thinking it might

😂😂

Ahhuh!

Was about to make exactly this comment, but you beat me by 6 months lol

nice one...

@Neil Dickman I thought the same

Rocket + Science = Rocket Science :)

Xtinct- ohh nasty, a compartmented glass bottle with one half the base and a quarter of the reactive chemical

Buran-Energia.

Y e s

the reason of it not showing any intresting things when you narrowed up the throat was the 1) the combustion chamber or the place before the throat where reaction was happening was way to big and thus there was not much pressure built up to fire through the main nozzle 2) the throat to nozzle ratio largely matters when you deal with bell nozzle engines here the nozzle was way to big and what happened was the pressure in the chamber dropped too low and thus causing the the air to come in from outside which slowed the reaction and thrust. this is why the flames was not close to the walls (glass) 3)the shape of the part after throat was not well for fluid mechanics. if you see very carefully the throat the place just after the throat you would see a huge empty space between the flames and wall which should have existed these were only which i found out being a noob in the subject but yes i could say if he had done all these he might have blown everything around and even glass would not be able to handle the pressure in the chamber

Finally. Now I can kill the Wild dogs here

It`s Waaaaaouuuuhhhh

Sounds like a karen

no 4:20

This is underrated 😂😂

Man... can’t believe I live within 10 miles of this man

It really be like that

Usik Kurchatov Good luck.

no, in the real life i used 20lrs LDPE and get only 50gm

Blah blah blah safety kids! Fun nazi

@@CamRStanford Not sure if you're joking, or actually completely ignorant as to how dangerous hydrazine is. This isn't the "oops, we spilled a bit, better put on some gloves" kind of stuff, it's the "oops, we spilled a bit, guess we'll all die in five years of acute leukemia" kind of stuff.

I've read The Martian, you don't need to convince me that Hydrazine is terrifying :)

@@Warriorcat49 Mmmmmm, the sweet smell of unsymmetrical diethylhydrazine...

Is that level of PPE only neccesary for occupational hydrazine exposure? Keep in mind you work with a *lot* more hydrazine on a daily basis. Nile has a fully equipped laboratory, I think he knows what he is doing.

yes. just yes.

MMMYUMMY

No you dont

I hate Drew Saddic the solid rockets on the side are the only ones used at the time of the photo.

The liquid motors are firing too but as they burn hydrogen you can't really see the exhaust product which is mostly water

Joël Marsman oh true. My mistake.

Ikr

Why is this so hard? It’s not rocket scie-oh wait

Its not really RFNA, it contains comparatively little NOx.

I believe those big ole red/brown clouds the reaction produces contain a ton of NOx, sir or madame

That is correct. But thats the reaction product, not the reactant. This NOx generation will be the case with either RFNA or WFNA.

Still its a small ammount so its ok...For science! XD

I wouldn't work with it without a SCAPE suit! Those are the space suit looking things you see in pictures of satellites being fueled, like this one: sci.esa.int/science-e-media/img/80/Planck-fuelling_027.jpg

But then again, I am a coward.

I would say just don't use it (especially when your test tube rocket is spraying it all over the place). It's not worth the risk for this little demo. There is a reason why most fully trained chemist (including myself) would only use it if absolutely necessary. NileRed, if you happen to read this: Please also consider that you are venting your fumes to the outside. I like your videos a lot, but using hydrazine in your setup would not only put yourself at considerable risk, it would also be reckless. Please don't.

For reference, my experience with hydrazine is from the Air Force. In the Air Force, all maintainers get trained about hydrazine safety if their job is related to an airframe that uses a hydrazine fueled EPU. To put how the Air Force treats this chemical into perspective, if the indicator swatch turns purple, a maintainer smells that ammonia odor, or a clear, oily liquid is pooling near the drains, the area around the aircraft is cordoned off (hangar evacuated if indoors), a ground emergency is declared, and HAZCOM and the base fire dept. is called. It really is no joke.

Aniline is also quite poisonous

Yeahhh 😂

It has to be

Almost. There should have been an exploding test tube in there somewhere.

Real horror is dimethylmercury

James Mueller same here I would love to just look at them

Could you post the titles/authors of some of the textbooks for some of the people in the comments?

My Chemist teacher currently asked me if i have any cool ides as last chemistry lesson before graduatin. So i showed her some things and also this, and we would like to try out some things and it would be rly awesome if you could maybe scan and E-Mail me the designs so we can think about doing this experiment if it's possible. Hope you answer me soon

He already did a few years ago. He made a video on how to make hydrazine sulfate, which was then used in his luminol synthesis video lol

I guess he didn't want to "choke" the escaping gases too much. If it does then we'd have seen the glass tubes shoot downwards off the stand. Or maybe they'll just shatter from the incredible pressure inside the glass tube.

@@guicky_ i haven't heard of the second one yet, here's to hoping it stays that way

@@transbiologistthetransesto7956 it might be more popular on my country, its like a naval focused version of war thunder, if you have heard of that one. can't think of a good way to describe it other then it being a very repetitive pay-to-win game

Hello brother

Atleast demonetized.

Why though?

@@E_Rico Because RU-vid's advertisers deem this too risky, may be used as terrorist how to's. See adcopalypse.

Because it's not a food review video with cancerous non-copyrighted music.

Or a clip from network broadcasts.

Overton Hallford He was using Aniline and not Hydrazine! :)

lol

How was the Air Force? :D

@@stevemc01 its amazing. Sex drugs and rock n roll. Get to fly jets every week.

Fuck yeah

Scott Manley, Codyslab, and NileRed collab?

Once the rocket is built, it can be offered out to the flat-earthers for some test flights. *Some* (a few) of them have generated appreciable funds so surely they'd be interested in supporting a rocket mission, right? RIGHT? :D

Throw in NurdRage in there for good measure ;) ;)

You could place a strain meter better the test tube and holder to determine the thrust produced. It can be made with aluminum foil and wire along with a couple of ohmmeters.

Nah, he's not using Chlorine Triflouride, so no need for the shoes....

yeah, those are for fluorine - metal fires

@@srenkoch6127 Then again, you can never be too careful... :P

​@@srenkoch6127 O2F2 is also fun, affectionately known as "FOOF" because that's its chemical structure and the sound it makes if you pour it on almost anything that isn't a properly fluoridated steel tank.

Does nobody get the reference?

that wwould be freaking dangerous cuz the reaction is very fast, maybe putting something like an inverted dynamometer would be safer

A spinning wheel of acid and Fire!

@@henryD9363 if it spun freely sure, but you need something to measure the force...

@@jacker372 You don't need to add something like a strain gauge, if you simply record its motion you can determine the force. See ballistic pendulums for example.

He can probably get out of danger if he kept the tube at an angle and used a Teflon tubeand a syringe to inject the acid from a range.

Sissy

Lmfao

fire shoots out of your "tube"? Yikes

Lol ur not wrong

Reminds me of the time I was dated to eat a habanero before a test when I was in school

A mushroom cloud can happen with any reaction that generates high levels of heat it’s just not as visible as with a nuclear weapon

I guess it is rocket science.

Is the starting of it.

@@MyuFoxable True.

we all know how you feel.....

you could have waited only one week and 6 days maximum if you subscribe on Patreon now!

Wait, so it isn't his scream?

And.... a much greater possibility of explosions!

@@henryD9363 hence the thicker tube.

Or you could change chamber materials to metal and form the throat via metal spinning, then add an injector so it can run for more than an instant. And maybe add regenerative cooling channels. Or you could just make a rocket engine ;)

@@warrentb1 well that would be the ultimate goal, but for initial testing, it is nice to be able to see the reaction

Immerse test tube in water beaker to provide counter pressure and contain explosions.

Maybe that's because it has all the elements of a story? Both the chemicals where introduced, they met, end then there's the build up which is timed perfectly like a bass drop then explosive climax, then it slowly died down and we see the reaction ending Compare that to the right which does not have enough build up and has a rushed climax. Then in the end all we see is black and we were not given a proper conclusion. Sorry if my English is bad Ps: i also don't know why I'm replying to a 2 year old comment

@@Klbkchhezeim That is genius

I'd think that removing the air would reduce the force of the rocket, since the gases produced by the reaction would first have to fill the tube before they could escape and push outwards. Might make the reaction slightly less interesting to look at. I also don't think the ice method would work either, since the surface area of contact would be quite significantly reduced, slowing down the reaction to the point where the energy would go into melting the ice, rather than pushing air out the top. It might also form a shell of carbon surrounding the ice chunk, preventing the rest of the reaction from proceeding. I suppose both options are worth a try, for science. But I have my doubts about their efficiency. Using a long tube to the bottom of the test tube might be a viable option, but even then, I think the reaction might be blowing the drops of both reagents out, and I'm not sure that would change. I think it might just flip which reagent is thrown out the top. If the aniline is added on top, the reaction occurs between the two "layers", blowing the aniline out the top, but if the aniline is introduced to the bottom of the tube under the nitric acid, he might find himself with nitric acid flying out the top instead. I think that might be the reason he's adding aniline to acid, rather than adding acid to aniline in the first place. Just my speculation though.

the ice wouldn't be in a chunk, it would be ground up, almost powder-like. if that was dumped in on top, its possible that all the aniline reaches the bottom before ignition

is this also the reason why the mixture ignites twice? because some of the aniline is blown away but then it falls back into the remaining nitric acid?

I think the analine might need to be vaporized to properly combust. What he really needs is to feed it into the combustion chamber along with the other reactant, atomized, at the appropriate volume flow rates and with enough pressure (and/or a one-way valve) to keep the feed lines flowing in the positive direction. I don't know if solidifying the analine will be conducive to proper combustion. Then again, creating a constant, stable flow from feed lines is a much more involved engineering project. I like the rocket engineering, but, as a chemist, I think Nile's work should probably be focused mainly on the ratios and phases that yield the best combustion. It would be more mechanical engineering to get into delivery systems that produce such conditions in the combustion chamber. If he wants to get that deep into it, I'd say more power to him and definitely watch the video with avid interest, but it would be a little out of his usual wheelhouse.

Aniline*

I, too, would be excited if I knew this was coming Mr. TheJewboy68

He made phenylhydrazine and hydrazine sulfate. When it comes to safety those are a world away from pure hydrazine (phenylhydrazine somewhat less so, but he made a tiny amount), which is what the rocket fuel is. Hell in the start of the hydrazine sulfate video he says clearly he will not be making pure hydrazine because it is too dangerous. Just look at NFPA 704 for hydrazine vs hydrazine sulfate, there's no comparison. And then there's the part where he wants to use it in rocket experiments, which means not just leaving it in a container but getting it everywhere. Yikes.

So fun fact, hydrazine is used to add hydrogen to BWR nuclear reactors to prevent oxidation

Why I can't give this comment 1000 likes?

Could be wrong, but I think that was solid rocket fuel Homer Hickam was working with. You wouldn't want "goopey" fuel in a liquid rocket (from what I remember in the movie). That said, I don't see any reason why solid rocket fuels should be off the table for these videos. From a mechanical engineering standpoint, they're much simpler. Still very interesting from a chemistry perspective. Perfect for NileRed.

@@sciencecompliance235 Yes, Homer was using solid fuels (black powder, potassium nitrate/sugar, zinc/sulfur), but c'mon, everyone makes solid fuels now, it's time to progress!

Wiktor Guzowski Well, as I see it, liquid fuels aren't really any more interesting from a chemistry standpoint, perhaps with the exception of hypergols. They have performance benefits, though, but are much more complex mechanically. I'd love to see a working amateur liquid-fueled rocket, but I don't know if that really dovetails with NileRed's RU-vid channel. That's more of a mechanical engineering endeavor.

@@sciencecompliance235 I'm actually working on an amateur liquid-fueled rocket with my friend. Please follow @JagielloczykAe1 on Twitter to follow our progress.

I'm happy with every upload we get. Let him do this on his own pace .

I dont. Quality > quantity

Hes alone doing this research. Rushing for videos is a good way to get dead.

I'm not trying to force him to upload more often or rush him in any way . I'm just saying that I enjoy his videos so much that I wish they were more frequent . It's like saying "I wish I had a million dollars" you do want it to be true but you're not expecting it to happen .

Fair enough.

Dr. Stone still hasn't reached at making rockets lol

El topo Brujo post pics of hand

You can find PDFs of Rocket Propulsion Elements online if you google it.

Yeah, I've had a rocket explode because I put a too restrictive nozzle on it.

@@ThomasPlaysTheGames In other words, the internal pressure is too great and the nozzle throat too narrow for enough pressure to flow out.

Mate. I'm a large way through getting a degree in aerospace engineering. I know about pressure imbalances - I just hadn't bothered to do the math because it would be interesting regardless of how successful it was (plus it was a ground engine test). edit* I had no intention for this comment to come off with a passive aggressive notion.

The test tubes should probably be a hair shorter. The gasses were expanding quite a bit before they hit the throat. Still a pretty cool demo for a first attempt though.

Uriah Siner Of course, past a certain length, pressure would decrease past maximum possible. I think what's more critical is just atomizing/vaporizing the reactants such that complete combustion occurs more efficiently, and less tube length is needed for the reactants to completely mix. With large droplets or pools, reactions can only occur at the interfaces between reactants. By atomizing, you increase the effective surface area capable of producing contact between the reactants, minimizing the need for a lengthy tube through which heat and dispersion vaporizes and atomizes the reactants that started in the combustion chamber as pools of liquid.

what? I don't understand your english

@@mitchellroberts7954 hydrazine is extremely toxic to all forms of life.

In Finland that mushroom is a popular delicacy, after VERY carefull preparations of course.

Let's give you my interpretation, "Miligrams of hydrazine on a person's skin can cause liver failure. A spacewalker's worst nightmare is hydrazine on his/her spacesuit, since the only way you'll be coming back through the airlock is naked. Interestingly enough, it's also a defense mechanism for some varieties of mushroom."

Dr. Medic You're a hero.
