@@prurobloxean27Yeah pvc shards are really dangerous. Be careful! Always take appropriate distance. Please wear eye and ear protection.

@@laboratoryofdavid I agree

Good point. I don't understand why it never occurred to me that ammonium bicarbonate could be used. Maybe I'Il try it in the future. The video was meant to be a proof of concept, rather then a practical approach.

I gave my reaction some more thought and I think the following happens: 2NH3 + CO2 + H2O = (NH4)2CO3 Ca(NO3)2 + (NH4)2CO3 = 2NH4NO3 + CaCO3 So it seems that I probably made ammonium carbonate in situ. So it makes more sense to start with ammonium (bi)carbonate. Thanks for your comment!

@@laboratoryofdavid the only drawback of displacing calcium is that calcium sulfate/carbonate is somewhat more soluble when ammonia ions are present but you could still remove most of it by filtration.

@@laboratoryofdavid yes ammonium bicarbonate is made in situ

It's pretty good safety wise 😂

sto guardando anche io recentemente questo video e apprezzo che pure tu stai cercando informazioni, essendo che neanche io lo sapevo ho cercato un pò e si tratterebbe di poliisobutilene, in sintesi una gomma usata per le ruote delle macchine e i palloni

molte grazie@@siegesschandel

Good question. I've never had any headaches handling ETN. Maybe because ETN is a solid and nitroglycerin is a liquid, its absorbed easier through the skin.

Thank you! Yes a glass retort can be used without any problems. Maybe a little less efficient because it has less cooling than a liebig condensor.

@@laboratoryofdavid Yeah, I agree. I don't have a distillation apparatus with the Liebig condenser, so it might be a great idea to use something else. Distillation apparatus is rather expensive to buy in my country :D I used improvised distillator with a small glass pipe to make nitric acid previously, but I want to use something that fits more than 250 ml of reagents inside :D

@@sprg42 Good luck! The price quality ratio from Ali is really good. Hopefully the retort stays in one piece during shipping.

@@laboratoryofdavid Thanks! I hope so. Where have you bought your distillation apparatus?

@@sprg42 Also from Ali! But it was several years ago before VAT was included in the price....

Hahaha, please don't taste nitroglycerin. But I can imagine it being flavor explosion...

@@laboratoryofdavid Hahaha! 😂 Tbh, in theory, I may have synthesised and tasted it out of curiosity when I was a teenager, not very smart. I was just curious because my father used to have nitroglycerin (and ETN!) tablets for his heart. It still tastes sweet like glycerol. But then I got dizzy and felt my heart beating inside my head. That's what the medicine does according to my father so I knew what I was in for. Quite the experience, not even entirely unpleasant apart from the headache. I felt super relaxed for about 10 minutes but with a pretty strong headache and then it all died down again. It acts rlly fast but also wears of pretty quick. But in theory I just had to test the theory, theoretically speaking of coarse.

@@FOATE Hahaha great story, interesting that it still tastes sweet after nitration. Nothing beats the curiosity of a teenager. When I was 15 I tasted some rocket candy, but it didn't taste well. Tasted like extremely salty caramel.

Hahah if the motor was strong enough to carry one. Last time I made a sugar rocket was 4 years ago. Good old times...

@@laboratoryofdavid you should start making them again. As they say, there is no time like the present :)

@@TheFireGoose Haha thats true, maybe I will. I've always wanted to make one out of stainless steel so that it is reusable.

Filtering calcium salts is always horrible, especially with a vacuum They end up being so fine that they clog filters.

Never heard of that method before. I'Il try it sometime. Yeah a soda stream could work. Although I'm not sure if the bottle material is resistant to 25% ammonia.

The translation is a bit vague. But I think what you mean is that the effect of the etn on the wood block is too little. I agree on that but the block was laying loose on the ground. Next time I will try a more scientific approach. Interesting channel you've got.

Just saturate the sodium bicarb. You'll need to add it incrementally, testing pH each time after mixing. I'm concerned anyone who needs to ask this, is messing around with such things honestly.

Quite concerned about his safety

@@laboratoryofdavid Yes. The saying a little knowledge can be a dangerous thing, specifically relates to high energy chemistry. I've been engaged in the field for 45 years, have a reasonable chemistry and physics education though and I've read many classics like Lancaster and Conkling. Both these and several more are on my bookshelf. I also had Tony Arena as a mentor, something I can boast about in any company. I've had some close calls. I've never injured anyone, including myself. I have all my limbs, fingers and eyes. I know many professionals, which I was once, and the majority who've been in the game for more tjan twenty years are missing fingers, a hand or wearing an eye patch. I once commented during a pyrotechnics seminar in Queensland, that with all the eye patches, hooks for hand and wooden legs, it looked more like a pirates conference. This is not a field you should get involved in, unless you're serious, and either have at least a very good grounding in Redox chemistry, or are committed to getting this in your toolkit before getting too hands on, you're probably going to maim or kill yourself very suddenly and without any warning. Many of the RUclips channels posting these experimental fireworks, pyrotechnics and explosive videos are insanely foolish. Separation distances are often ridiculous. Lab techniques and precautions are horrifying and the very devices are sometimes very, very illegal for well established and often historically lethal reasons. The max size of salutes worldwide, is 3 inches. Any bigger and you're playing around with something that's far more hazardous than it is going to be entertaining. Many mixtures are unstable in the way they're shown. Those with the knowledge ate aware that it's OK if you're going to use the composition right away, but will need to stabilise it, in a specific way differently from one mix to another. Many rules like this are simply taken for granted and may not be mentioned by someone who knows this. Those who are knowledgeable and experienced will bend a lot of rules too, because they know the safety margins, or are familiar enough they account for factors in other ways. So I see some very competent people being talkes down to, by people who know some safery rules, but not much about the details and their assumption they can do better is poorly grounded in fact. Anyway. You only die once and blowing yourself up by miscalculation of the risks and your knowledge, is as good as any way I suppose.

@@GrassPossum What do you mean the max size of salutes is 3" worldwide?

Some people are interested in explosive chemistry.

@@laboratoryofdavid Total Agree ! i'm working on it me too , check my video if you want :) i will post more frenquently

Some of us have hobby interest. I'm a retired professional, but started experimenting. Now I'm back to that. Not everyone likes the same toys.

Glad you liked it. Yt doesn't like nitroglycerin synthesis videos....

@@laboratoryofdavid police might come knocking or not knocking 🤔 if they know you're making it. I guess it depends on where you live

@@SodiumInteresting , never had any problems with the police. Been making energetics for four years now. Normally I make and destroy the stuff I make so they don't have any evidence of any explosives made. In my country RUclips videos can't be used as evidence in court. So I'm quite safe in that regard.

@@SodiumInteresting Hahah once they have you on the radar it's hard to get off it again. Non energetic is also very interesting. Always something new to learn and try.

I appreciate that

Oh nederlander zie ik nu, leuk!! 🙂

@@Voske85 altijd leuk om een Nederlander tegen te komen. Compositie van m'n plastic is 90% ETN 5% PIB (droog) en 5% 10w40 motorolie.

It wil make your blood run more easily ;) HDPE is a better option...

Thanks, sounds like a long project. It would be a nice proof of concept.

You could get trigricerides from soy beans

im gonna using bacon

Ain't pretty but does the job

Best way in my opinion is via amonium nitrate and 98% H2SO4. Only if you have access to ammonium nitrate. Otherwise use KNO3 but this will form hard clumps of potassium bisulfate which are hard to dissolve. It could be that your nitric acid isn't strong enough. Don't waste your precious acids on nitrocellulose ;)

@@laboratoryofdavid what is something better to do with them ..?

@@aaron5632018 Like PETN, RDX or nitroglycerin for example...

@@laboratoryofdavid ohh yeah, durrr

even this nitrocellulose isnt ideal as shown by the residue on deflagration, if nitrated will the stuff just disappears instant, no fwoosh should more of a poomf sound. I need to do some shock tests on my nitrocellulose as its super nitrated but the sensitivity seems about average

Can't disagree

Powder?

not powerful, primary explosive so dangerous, and overall very sensitive so it's not that good. Not to mention that it can become the heart attack poison if too much on contact or eaten

@RandomBacon-mz7ci careful planning and handeling is key. Pre chilling the acids in the freezer significantly reduces the chance of a run away reaction.

Hi, Motip brake cleaner

zippo gasoline is quite successful, normal gasoline is successful but very smelly

Use rats glue or paraffin

Are you talking about polyisobutylene?

Thanks! It isn't a reliable method though. But if it's all you got or wanna deal with it is doable.

A small quantity of HMTD is enough to detonate any explosive if is closed in metal container.

@@nicoschadjidemetriou4373 yeah it is, but HMTD is a little dangerous / unstable for my liking. Now via personal experience and research I do understand that it isn’t as bad as it’s made out to be, but there are still many safer primary’s out there. I for example use silver acetylide (double salts) cause it’s very strong, pretty inert to impact and friction + static, easy to make and most importantly stable. But there are loooaads more out there.

@Mrgoosepoo. We are learning by experimenting. You always put the detonator the last moment. In 1963 I was 17Y.Old i filled iron corner of half inch with TNG (in wood fillings) and trinitronaphalin. The detonator was Potassium Clorate+Sulfur. I dropped it in a covered hole. I didn't imagine to be so strong. I made and mercury fulminated half a gramm. It is very easy.

@@nicoschadjidemetriou4373 very cool. Although you say the detonator was potassium chlorate and sulfur? How did that work? Did you simple ignite with a fuse?

Haha thank you man! I'm trying to trick the yt algoritm so the video won't get deleted.

@@laboratoryofdavid ik, im just playing along

Thanks! You have a nice channel.

I think you're right. It was more a proof of concept. I've had succes with rocket candy and slow burning potassium nitrate flash. For normal detonators I use CHP anyway.

Slow burning? You want something faster if detonation is sought. BP is rarely fast enough to act as a primary.

​@@GrassPossum a heatshock etn detonator is sort of a nped, its like wrapping etn in foil and putting it over a candle, it detonates with great power. What he is doing here is just the same but instead of a candle you use a hot burning mixture.
