I think he's personally planning on watering the tree, if you catch my drift. XD
@@QuippersUnited he's a libertarian, I haven't gotten a direct answer but he hearted a comment that i wrote saying I think he's a libertarian.
So he's just putting information out that we all deserve and where that goes it goes.

"Well, I wanted to find a better way to find and remove a splinter from my finger. After some research we decided to build our own MRI chamber, so I started to do research on it and it turns out that to generate magnetic resonance images you also need so-called Perchlorates, which is a chemical compound also found in the surface of Mars in rather large quantities. So we turned our anechoic chamber into an interplanetary spaceship. And that‘s why we launched a colony on Mars so I could take an MRI of my finger, which altogether is also cheaper than your regular MRI facilitated by the US health care system."
We found the same problems and just bought one on Amazon.
@@TechIngredients The spaceship or the finger?

So a good learning, and i can skip doing it myself. or
@@Kenionatus yes
I have just come back from Mars, the big problem was getting the stuff past customs on returning, that cost more than the fuel and meal service during the journey.
I would have paid to have a teacher like him in high school. An hour long video that seemed like 10 min. Thank you for your hard work!
Indeed same feelings, such easy introduction and very interesting!
hes our new mr wizard loved that show as a child, when i thought as a child, acted a child. since becoming a man ive had to put away childish thing. tech ingredients fills the spot perfectly
At mine, high school, in the 80's & early 90's they taught some of these ways chems can be used. No more, just that America is an evil country & it should be hated. Very anti-commie back then too. Now they're top professors at many universities & even sooner. Not too pleased or optimistic about were we'll end up if this socialism/communism popularity continues and isn't countered with how America is quite awesome . But these schools, constantly teaching our own children to hate America and only look at the bad things that happened. Not gonna be a recipe for survival
I had such a teacher back in HS. I don't remember the reason, but in class he created a little NI₃ to spread out in the hallway. You know, that fun stuff made by soaking iodine crystals with household ammonia! DON'T try this at home if you know nothing about it.
He disappeared from the school's faculty the following year, and a couple of years later I was working as a grocery bagger in the local market while he was a shelf stocker! The owner of the market sat on the school board that probably had something to do with deciding his career change!
Absolutely amazing how he keeps the presentation coherent without pauses or edits
I’m almost 50 years old and it’s amazing how you have inspired me to take up chemistry as a hobby now at this stage in my life. Thank you and please keep them coming.
Great!
Will do.

As a Veteran Air Force Rocket Fuel Handler I found this video really fun to watch. I used to work with UMDH hydrazine and N2O4 nitrogen tetroxide. These were extremely dangerous and poisonous chemicals that we worked with in amounts in the tens of thousands of gallons. I would love to spend a day in this guys garage.
I salute you, Air Force Veteran too. Love to get ahold of some jp4 if I remember right, in Duluth back in 78 - 82.

With everybody else in primitive "space suits". Keep an eye on that weather vien, so you knew which way to run. I think 1/2 of those Old Titan II would blow up in the hole if they tried to launch them. Using them for sat launch vehicles proved me correct.
"it's nice to know you could" I loved that comment
That attitude is why i come back even if I’m not ever going to do this.
Having made rocket motors that large - yes, they're awesome, but also a little scary haha.
It was the smile that accompanied the comment that made me laugh!
Nevermind then

TH-cam algorithms may not prefer your super detailed longer videos, but we do, thank you for putting us ahead. Respect..🙏
I remember when I first found your channel, it was at the very beginning and immediately subscribed. I was so afraid you might not get traction and shut it down. I'm so grateful others have found as much value in your channel as I have.
This video was the same density of information as my university lectures have, except the topic is really interesting so watching through a whole hour is done with little effort. Kudos to you and your team!
First recommendation of this channel for me, the algorithm has been sleeping on the job.
Within two minutes I'm thinking "why am I not already subscribed to this guy?"
Then he puts emphasis on safety, then he mentions Scott Manley.
*C'MON TH-cam, YOU HAD ONE JOB*
Anyway, subbed. Thanks.
He has also made moonshine, speakers, a boat, drones, an anechoic chamber, and military grade smoke bombs. Next up is a magnetohydrodynamic drive nuclear powered ballistic missile submarine he will sail up a river in Maine.
Same story for me too!
I found it when i searched for specific educational content that he had done. Maybe try... looking? Lol.
@@sheldoniusRex Nice reference. ;)
Some people have Die Hard as a Christmas movie but for some reason I always find myself watching that one instead.
@@nicewhenearnedrudemostlyel489 I understand how search works. The point is that based on my existing subs and watch history, TH-cam's recommendation algorithm should have been pushing this content at me years ago but for some reason I've never seen this channel pop up until now.
I'm going to go out on a limb here and say you're probably on a first name basis with your local ATF agent. I'm kidding, of course. But I do hope you hit that last 5k before the New Year. I can only imagine the amount of work that goes into this channel, but I can definitely say it shows. It is far and away, one of the very best of its kind on here.
Thanks!

We all know he is lol. His name is mentioned at fletc. So I'd say yeah. Fun fact... 😁
@@fu6461 seriously? That's pretty rad. Hopefully they like watching for the science and high production value rather than looking for a chance to "gotcha".
@@TheConstantComet yes. It is very educational content. Better than any university class 😄. Gotcha is whatthey are designed for. Those people have no heart or intelectual interest, they say ir act as if they did but the reality is not the same. Sad but true reality. That's what 🇺🇸 has become, a fear based community. Hopefully one day everyone will just get along and leave each other alone.
Had fun with Estes rockets as a kid and later got my daughter into it as well, but my dad always used to say that he refilled his own rocket engines back in the day. Finally got to see what's involved. Thanks much.
I can't believe this video is more than an hour long.. It felt like ten minutes the way it just sucks up your attention. Absolutely amazing quality! If chemistry classes were like this in my high school I would have been a chemist right now.
I watched this on Christmas Eve, and here in Sweden we give the gifts on this day, and this video was like a real good christmas gift. I was like a kid, "yes, yes, rockets! Yippie!!".
I agree. Thank you from Sweden.
I have to agree twice cause in Germany chrismas eve is the night that counts - for adults and children.
And same for the video that I had seen in the hour it appeared and loved the progress and evolution in all details.
Spend the whole video to make sure to understand the big points.
But a lot of people will run in trouble here due to the chemistry if you order too much and online cause what is great to power a rocket is also great for a bomb and we had a swedish guy buying ingredients online due to his hope swedish restrictions would end at the border. But seem to be EU regulations behind a curtain that kicked the trigger.

This was phenomenal. The camera zoom and focus were great. This was an extremely professional video and incredibly informative!
Having voiced my concern and surprise about ammonium perchlorate, I have to admit that this guy or outrageously detailed, and well spoken. I appreciate this.
This channel has to be the best for us slightly unhinged nerds and geeks who just love to experiment. I've even done some of this stuff myself, but nowhere near as well! He's like the dad we all wanted growing up.

Probably the most intuitive introduction to practical rocket science one could find online.
Want a much more detailed explanation of solid fuel rockets: th-cam.com/video/jATkV8HE2sQ/w-d-xo.html
Watched it. its not a detailed explanation at all. Just a consumer news service level record of a test day for SLS Solid Booster. The only part I found interesting was the 2 minutes showing the geometry of the grain port... th-cam.com/video/jATkV8HE2sQ/w-d-xo.html
@@bencoman I found it to be laced with design tidbits throughout, but no, it is not a how to build your own with blueprints and fuel formulae.

@@bencoman What part of "intuitive", "introduction" and "practical" you don't understand? I can help.
Absolutely love your vids. I will probably never build rocket engines but I sure enjoy watching the process . Very informative , well made super detailed video. Thank you for sharing your passion with the world . Very inspiring stuff !
We all wished for teachers like You. Now I am old and not as interested like a kid but I still wish for more people like you with passion and great skill in telling what you mean to convey in understandable and interesting manner.
No BS with this channel. All business. I respect that a lot. Thank you for the excellent content.
When we were growing up, imagine if we had access to teachers like him. How many more of us would have ended up as scientists.
I did. Obviously he couldn't get into anything this dangerous, but he was extremely hands on and already pushed the boundaries of what the school would tolerate a bit. Honestly they probably would've nixed him if they thought they could find a competent replacement, but that area was notoriously stupid.
Yeah the people in power who control the educational system don’t want a bunch of smart people haha that’s like there worst nightmare
Dude I’d be able to build a fission reactor out of grass and portal ray gun that’s a wearable like watch for the consumer market by now if he was my science teach .
Yeah, but given that he's a white male, the "woke" cult driving our cultural norms would have considered him as evidence of racism & "toxic masculinity", and fired him for someone who is far less competent at teaching/inspiring students, for the sake of "diversity".
Bill Entley. Best teacher in my entire academic career. Taught high school physics, and you could tell he actually cared about making you LEARN something and not just giving you a grade. You could also tell he was one of those kind of people who was so smart it was kind of scary. And also funny as hell. And ugly as a can of smashed assholes.
Great video. Very thorough. I used to make sugar rocket engines when I was a kid. I like that you played around with different oxidizers and catalysts.
Wow, this video was outstanding! Thank you so much for teaching us in such a great way. I love your meticulous explanations, your care in showing us every detail of the process, and your eloquency. Greetings from Germany :)

I'll probably watch this several times over. Last night I put it on with intentions of falling asleep to it. Otherwise I'll lay awake
Muito bom hahahahaha. Sou Brasileiro, vou fazer isso daí.
I'm reasonably certain that I could follow your meticulous instruction over a radio...you're BRILLIANT at how you convey your subject matter! Thank you!
I do actually listen to his videos while I'm driving or working.
Awesome communicator. He ought to be a High School science teacher to inspire the next generation of engineers.
I absolutely love this mans channel. I can watch it on fast forward and catch every word because he speaks so eloquently; covering every step and bit of information with such a flow.
@@disorganizedorg How about president 8) I'd vote.
Nice 🪐-Saturn-🪐 imagery in your opening sequence logo -Tech Ingredients-. For any curious its the image of the Hard drive inner disc with ring imagery. 💽.
Nice to know. .
This video brings back memories of my JROTC training in high school. We spent about a week on rocket engines. One thing I remember is you can change the shape of the central void in the grain to vary the burn rates. That was almost 40 years ago, so I don't recall any specific shapes in the text. I can visualize how a cross or star shape would burn differently than a round hole would though. Great video! 👍👍
End burn without a hole is slow, round hole is fast, a star is fastest because of more surface area.
Wow I sure wish this would have been available when I was exploring rockets back in the 70's. Great presentation ..
Yes! Great to see another long-form video from you guys!
Love your channel man keep up the great work
@@jhondoux84 Thanks man. Good to know you enjoy it!
@@jhondoux84 i agree
Also love your channel !
I wonder about a capacitor discharge to ignite the rocket
when ever I see videos of someone who is quite big on youtube trying to make sugar rocket motors, they tend to make a lot of mistakes or just have poor methods. you pretty much nailed everything. only thing i can say is give tips for improvements. you can use a few drops of sodium laureth sulphate/ SLES (the surfactant in shampoo and soaps) to thin the fuel as much as possible. Richard Nakka has a video detailing its use. You may also want to try making a reusable motor out of metal. this will allow you to only need to make fuel grains for each firing. With regards to storage, its best to store it in an air tight container with desiccant to keep the fuel dry otherwise it will pull moisture. the only fuel I've ever used that just does not pull moisture uses erythritol. Another thing is that fuel with iron oxide in it does not store long term, it does something to it that causes the motor to always explode. anyways. good video
ElementalMaker just drills the hole in propellant. Rocket made!
@@ncdave789 different type of motor.also thats the worst way to make a rocket motor
using fuse to ignite 'and run' from any experimental rocket motor is flirting with danger and how many are injured/killed
@@mojaverockets I'd be tempted to make a core alignment jig. The reliability of these engines is contingent on many things. One of which is the reproducibility of the core. Simply jamming it into the molten mix will, eventually lead to a CATO of the engine at worst, at best unreliable motors. Also, it would have been nice to weigh the test composites to at least increase the chances of comparing apples to apples :) Anyway, always enjoy your work. Stay Safe and Stay Well.
@@ncdave789 just because your big on TH-cam doesn’t make what your doing safe
Hello Sir! i just stumbled upon your page. I absolutely love your technical descriptions for everything you do. i have been in hobby pyro for all my years. professionally licensed shooter when i turned 18. over 20 years i have been exparimenting and dabbling in alll sorts of different compositions. your channel is inspirational and i will continue to watch and learn! thank you
How nice, back in the day we did not have all this fancy modern way of building model rocket motors. Our casings were roll with glued paper bags over maderals. They hardened after a few days, the had to be inspected and sized, plugs and nozzles were made from pounding fire clay and grog with homemade maderals, all our tools had to be made as you could only order the chemicals, scales, and things already available for other uses. It took much longer to do this and then build our own Dinamo meters to test thrust out put, but that only came after hours of testing motors under ground due to many failures. It was fun and I put many years into this until I had a reliable safe motor to use. What you have to now and just order is incredible to me. I wish I could start over, but I have to many medical issues right now. Good video, nice safe shop you have thanks for passing this down to next generations of young people. I still hold a certification in High Power Rockets, mostly as a donation. Although I might attend the LDRS in Black Rock if I am well enough. Thank you.
Very rarely can someone captivate my attention for so long ( i normally realize that they actually know less then i do lol ) but you sir are a different animal. I like your broad knowledge and the way you have to clearly communicate it. We feel your passion, and it shows in your videos. Thanks you so much and Merry Christmas to you too!! Looking forward to see the motors thrust test result!
Yeah, I don't watch TH-cam to learn from myself.
I agree with your comment.
Always a good day when tech ingredients makes a new video!
So informative, it was sad not really being taught chemistry and so much of the world being confusing early on. Amazing creators like you give so much understanding to the people in the world it's truly incredible.
how the internet should have always worked (instead of being conscripted by people with evil in their heart -mostly conscripted and my opinion solely)
This gentleman is teaching engineering for free. such a valuable lesson with practicals. WoW!!!!
This man was a born instructor. To make such a dry subject interesting and informative at the same time is a talent few people possess.
He should do a colab with Tim Dodd...
Have you watched John Dobson build a telescope from scratch, grinding down a piece of glass by hand. The video is here on TH-cam and well worth a watch, th-cam.com/video/snz7JJlSZvw/w-d-xo.html
He's definitely knowledgeable, but drying paint would be more exciting. I watch because of the information given.
@@satyris410 Thanks for the link.
@Ivan Jakanov Its literally rocket science
Thanks for showing safe procedures for handling these materials. Some friends were careless making rocket candy at the beginning of the year and started a fire.
igniting any experimental motor with a fuse and run is probably one of the most dangerous things that can be done in rocketry and has resulted in numerous injuries and deaths.
Thank you! I thoroughly enjoyed all experimental sciences ny whole life. But hit a big depression era ss I turned 41. Your videos have been drastically helping reignite my science spark again.
Truly Thank you!
I did so enjoy your presentation. Good job. Started trying to construct rockets in 1957. We would skim match head material and place it in small tubes of paper. Do not think we ever got lift off. 73 years of age now and fortunate to be here, intact. Couple years later we did a match head piece of 1/2 inch copper tube. Got our attention. Even did some stupid shit in VN. Big fan of black powder as well the flash powder. Grew up with original Cherry Bombs, M-80's. Still have some supplies, scales, grinders. Getting warm in my area, so many projects on my list. In highschool we were scraping Pidgeon shit off tree limbs for nitrate. Enjoyed your information as well the delivery. Thank You.
One of the few creators that gets an automatic like before I even watch the vid. Huge amount of respect for this channel.
I appreciate yours and your son's enthusiasm in your projects and dedication to completeness.
8:00 - in all the years I've been watching science and rocket videos on TH-cam, you're the first person I've seen who's explained rocket thrust in this manner. Everyone else just talks about Newton, conservation of momentum, reactions, etc. None of this actually explains thrust, this explanation does. I first came across this explanation in a children's book on space flight - I think it was in 1968 or 69 (not a coincidence - everyone, including 7 year olds, were crazy about space flight and rockets back then). The thrust would be the area of the opened door multiplied by the pressure (or pressure differential) in the room. Excellent!
Ive been brainstorming a rocket glider for months. I hadnt thought about using a slow burn motor before! Thanks!
Always appreciate when someone way way smarter than you decides to take the time and care to teach, simply because they want to share the exciting things they know with you.
Weak
Your long videos are fine because you don't pad it out with pointlessness, every minute is worth watching.
@fkujakedmyname As a design engineer I appreaciate the thought process that goes into their design descisions. I can see you may have passed high school. did you get much further.
This was exceptional! Kind of amazed when you picked up the Ammonium Perchlorate, being familiar with that stuff, as I did not realize that it could be obtained outside of the Space Program. We in Henderson, NV. remember that stuff. Last amazing videos of yours I saw were the SPEAKER panel tests. You are an incredible teacher!! Thanks!
Awesome, thank you!
It's fairly easy to get it outside of commercial use, but most suppliers still want see some credentials just to be reasonably certain that you're not some random nut job that will cause another round of regulatory scrutiny.
I know a chemist that got a visit from the FBI for ordering oxidizers, and it was probably just a routine audit and their name fell out of the hat, and nothing happened. But they are watching and companies do want to protect themselves from liability.
I would like to restart my hobby once I get done moving. I would like to start at class 1 rockets and data collect and make the rockets smart. Recently I just came across your videos and they are very inspiring and I cant wait to start up again. So right now I am studying. Thank you for all you do!
What I learned today: When making coffee at the Tech Ingredients World Headquarters, be very careful when selecting the bean grinder.
Use the one labeled "fuel"... should be ok, lol.
I grind all my rocket fuel with a ceramic burr grinder.
Dementia-influenced situational awareness has its consequences...see Joe Xi.

Awesome Video your descriptions and explanations made it very easy to understand. I haven't made a sugar rocket in years but this makes me want to start all over again.
Benn watching TH-cam videos since it's inception. I like how your just about the ONLY 1 who does this step by step, without that monotone, virgin, clinically depressed cereal killer kind of voice. And ur the only 1 I'm actually going to donate to.
I love that you said to use a vacuum when machining the graphite nozzle and immediately thought to specify "vacuum cleaner".
Because this is EXACTLY the kind of channel where we might see exotic vacuum machining processes being applied!!!
You guys rock.
What got my attention was that you seemed to allude to the method of layering the different regression mixtures so a solid fuel rocket can lift suddenly, then accelerate slowly before hitting the fast regression mixture in thinner atmosphere.
I suppose it could be achieved, if You would have signigicant diameter of the rocket (quite big is necessary) and then wou would use some internal tube every time in different diameter to our the next layer of the fuel. PRocess would take few days, but it's achieveable.
That would work but is not relevant to a motor that could (easily) be built that way.
A serious issue with the plain hole through the middle is that as it burns the surface area increases, increasing gas production and therefore thrust. The "simple" way to get round this is to use a star shaped hole, the surface area remains constant, but would make layered manufacture very very tricky.
Having said that though, a layered approach would be another solution.
One construction technique could be like dipping candles. Each dip in hot wax adds a thin layer.
The use of layered propellants with different burn rates and ISP is used in solid rocket motors industry, generally referred to as dual thrust.
Layered propellants and combustion chamber designs are what the big boys use to achieve necessary thrust curves.
I love that the Ammonium Perchlorate mix burned for exactly 2 minutes. There is always conformity to be found among chaos
Great video, as always!
I am so pleased to have found your channel. You explain everything so well. You make it easy to understand what is going on. I look forward to watching more.
Thank you John
Time for a little _Rocket Science™_
*(literally this time)*
man has good taste just like his channel
*True*
It is and it is not rocket science.
it is because we are talking rockets
it is not in the sense that you use "rocket science" to describe something really hard.
Don't get me wrong, I still like a good explosion, just not too close. Or with too much flyrock or shrapnel, fleshettes or like that. You know, were talking recreational use.
First video I've seen from this channel. You're an incredible speaker. I can't quite describe it, but the way you've essentially spoken for an hour straight without too many cuts and in such an engaging, easy to understand manner is amazing
My respects and full support to this guy, his videos are extremely high quality, in both production and information, congrats and thanks
Thank you.
I absolutely love your analogy and way to "visualize " how a rocket works. You are an absolute TH-cam legend!!!
Thanks!
Burn times!
Standard: 27 seconds
Iron Oxide: 21 seconds
Slow burn: 2 minutes
That slow-burn propellant is really only good for a delay element, much too slow for rocket engines. Kinda shocking how long it did burn though...
It's not often a video of this length keeps my attention without skipping bits, but I watched every second of it. This is quality. Thank you.
Did similar experiments in 1972… but our firebrick was a gravestone (we were kids) Seemed the safest method at the rime… Thanks for sharing.
Just wonderful. Put aside a moment the introductions to some of the aspects of engineering and science........the patience, planning, homework, attention to detail, subtlty. If these are all a student absorbs, they have learned some very essential traits I hope are learnable. I'm certain I'm overlooking some. Thank You! Keep up the excellent work.
Magnetohydrodynamics is just an excuse to play with rockets. I like it.

What a great science lesson, and video!
Your commentary is concise, and kept my attention for the whole video!
i dont know what it is, but your energie just makes you watch every second without skipping or not paying attention. your the best science youtuber
Thanks!
Best pourable sugar propellant I have seen. The use of ammonium nitrate/potassium salt mix with sorbitol, impressive.
How about *Ammonium perchlorate* and *Potassium hydrogen phthalate?* _Crazy power!_
I just found your channel today and can I say, it's refreshing to see a person of science describing these techniques. I found dozens upon dozens of videos I will be watching and liking! Thank you for treating us as intellectual people but still teaching us in full. I feel like I'm back in university!
Superb teaching skills, in a fair world every kid would grow up with teachers of this quality.
Sir, you are a great educator and superb lecturer. I take a lots of pleasure in listenning to you.
I was waiting for you to make a "multiple stage" rocket by doing partial pours of all 3 versions into one tube.
You have a tone and punctuation in the way you speak most teachers would really fond over!! Simply charming.
Congratulations for the scientific spirit Sir! And thanks a lot for sharing your experience. Guys like Werner Von Braun, would have been proud of you.
Some of the chemistry involved is very complex, there's a lot of math in the depths, but he makes it for a great way to have people of all ages interested in science and inspired, and I find that is great!
A very well put together video. I build rockets also and never heard of the rocket motor company. I've always used thick walled cardboard and line it with graphite. I'll definitely check that company out.
So far, this is the most informative video I have found since making my own sugar motors. Very professional, not all hyped up. It's like watching my old physics instructor but this time I'm totally interested! :)
reminds of a cooking show when he brought out the cured stuff from under the table
and here's one we made earlier lol
@@WX4CB I don't know where you live so you might or might not be familiar with "Blue Peter", that phrase brings back fond memories…now I'm imagining John Noakes building an actual rocket 🤯
@@PhilBoswell yea i know... i'm from the UK (live in usa now though) but yes... as long as you use the sticky back plastic for the tube we're good. lol I wonder if he'll set it off in the blue peter garden haha
My chief chemist said chemists make the best cooks. Pretty much the same methods but different ingredients.
Howdy Sir, this is my first time ever seeing your videos… in the first 6 minutes i was super impressed, subbed and looking forward to exploring your channel… you seem like a super knowledgeable guy. Thanks for documenting and sharing.
I think you have the best TH-cam channel for (DIY) tech! I think if you put your mind to it you can do whatever project you want. I really like the broad information. Thank you so much!!
26:30 "Have a little bit more [sorbitol] and it makes an excellent laxative."
That's a different kind of rocket fuel.
I know a certain guy here on TH-cam that should have watched this before he made a video about propping half a kilo of sugarfree gummibears down the hatch and running around for the rest of the video farting and doing marathon runs to the porcelain throne.

@@thiesenf I think you're spot-on! And I might have downplayed the quantity it was 5 pounds ( 2,26kg's), jebus , after that torture your intestinal digestive bacteria have been mass-murdered.
@SBK Stóre Jebus, how many times did you have to view this video to spot that !
"Rectal Rockrets"!
I've not seen anything like this before, really informative and interesting. I quite like the engineering side of this. It would be great to see these rockets in flight.
Thanks!
You are the best when it comes to explaining what you do. Thank you!
When I was a kid in the early 80's I I pressed sugar + potassium saltpeter with a hydraulic jack into my rocket engines, this method blow my mind. You are the best !
Thank you for sharing your knowledge with us all. I really appreciate the level of detail you put into explaining everything.
First time on this channel, and I had to subscribe. This guy is a spectacular
natural teacher.
Everything about this channel is amazing. Thank you for this material.
My favorite cooking show.
Fascinating videos! I love how you just move from one subject to another as you please, whether rockets or air conditioners. Great explanations without filler, interesting content, and the most gorgeous shop! Inspires me to work towards my own someday..
Thank you so much, I'm so glad to have stumbled upon you. I missed my calling in high school because I was lazy. I have resparked my imagination and I'm gonna change the world with some new ideas in physics and chemistry. I'm 59 years old and I want to Set an example for others 😄I'll at least change the outlook of my family and friends
Sir: I wish you every success with your endeavours.
A very fine video. You are a great technical speaker. The pace was great. The presentation was clear. Well done!
