The Science of Pyrotechnic Effects - with Matthew Tosh 

Please mention the dangers of STATIC electricity also. People DO play with items trying to make a louder bigger effect, no matter how much warning is given. Great presentation all in all! Thank you. Love the inert product demo!

I love this channel, I mean I can't attend those lectures, so it's amazing to watch it from home!

Really good lecture - and nice to see the emphasis on not only being safe but teaching about safety.

As an amateur inventor, I discovered gun powder, while working on a H^2O fuel source, during the first OPEC fuel embargo! Unsure of my discovery, I raced to my local library & sure enough, I had the ingredients of gunpowder! Then, as I continued reading, I further discovered, that I was 3500 years too late! The Chinese had beat me to it!!!

Brilliant. Totally engrossed and enlightened !!

Love the enthusiasm! I wanted to be a pyrotechnic when I was in school. Great science background to the craft too.

At 47:35 He talks about colours in fireworks, just for anyone who's trying to learn about pyrotechnics that has to do with colours, like I am trying to.

The title had me at "pyro". Love these videos. Also 1:27 is how I light a candle, too. :D

Absolutely outstanding lecture! I had the opportunity to register for limited use of professional grade pyrotechnics, and had a lot of fun, but as Mr. Tosh describes, safety was tantamount to proper enjoyment!

Amazing lecture, great work.

They should've titled it "An Hour of Tosh" ;)

`First time I ever came across real Pyrotechnics ( being from England ) was when I visited Valencia, Spain - to see one of their Festivals ( Las Fallas ). My interest in this particular Festival was piqued when I read, in Rough Guide to Spain, that this is `probably the most riotous Festival in the whole Country.` Well then , whom wouldn`t... ? Hells` Bell`s - it is totally insane. Pieces of trees dropping on top of my head whilst stood a quarter of a mile away from the action. People being wheeled off to hospital to have their ears checked. In fact, the first time I was there I went behind a tree and put my back to it - thinking that the tree might adsorb some of the sound energy that I could feel hitting my chest. It surprises me that any Valencian can hear at all.

I'm 53 so I've see a fair few fireworks from the little box of standard fireworks when we were kids because cars weren't as common to get to displays in bigger towns, to organised displays. I'm concerned that way too many people buy fireworks that are too large for the garden/area they have.

What a great lecture, I love this channel!!

Very good presentation by Matthew with loads of information.

Wonderfully entertaining and interesting

Woke up to this playing. Watched the rest and subbed

Brilliant lecture ! Thank you Ri :)

I do love this lecture, but I wonder if you could enable them to be captioned, please. There should now be an option to allow others to add captions for you, or to allow RU-vid to auto caption and auto-translate. I'm hard of hearing, and from the US so trying to make sense of some of the accents and terminology without captions was a little difficult. Thank you for the great video!

I wanna feel an "Infrared Fireworks Show!" Cool video, I always wondered how you guys made some of the effects, like crackles, roaring, whistles, showers of sparks, designs etc. You made some pretty funny comments too! You've definitely got an awesome job! I'll be looking for any other videos you made!

Cool I love these videos. Glad I could watch one same day it's put up

awesome presentation

Interesting video. Pyrotechnics are always fun.

8:45 5 or 6? That's basically just like lighting a candle for a Rammstein gig :D

Great stuff thank you.

Who takes their kid to a lecture called The Science of Pyrotechnic Effects, then takes them out when there might be a loud noise? I understand safety is important but it's getting ludicrous how micro managed things are now a days. In the 70's you could walk into a chemist and buy the chemicals to make BP, which I did when I was 12. Pre internet I wasn't aware of the ratios, or the other steps needed to make proper BP, but we still had fun.

Great job !

Love this

I love his chanel because i like chemistry and fire

Well, TRULY wasn't very loud.. and it's on a home theater system.. maybe it's just I'm used to LOUDER fireworks.. or .you Tube has muffled it.

AHHHH, Clifton Suspension Bridge in Bristol!! AHHHH!!

I want to do this!

56:36 cool fireworks How to maid can you any tell me Which ingredient use

And now I have to watch the London NYE fireworks video again…

9 minutes in and all he has told us is how good he is. Get on with it!

I wish we could get some lectures aimed at adults

I enjoyed the lecture, but I was hoping for a bit more science and not just a pyro-show. Love his enthusiasm!

27:31 that kid just needs to listen when hes told DONT SIT IN THAT SEAT or you could give him a physical demonstration and just let him get injured

Any one know which chemical are used in indoor cold pyro?

I guess 44 Grandmas got hit with a whizzy rocket going "pbtbtbtbtbt"

I like how the people up the stairs are coughing due to inhalation of MgO 😂😂

Andrew Szydlo needs to show this guy how its done

As a former mine diver i did a lot of "fireworks" ... hehehehe

I don't know, I think he should have used 6 inch thick armored glass for the black powder demo.

SMILE.

no wonder he is an expert each time he talks, the words are exploding 🤣🤣🤣

The presenter needs to go to an Andrew Szydlo talk. While the safety aspect when dealing with pyrotechnics is understandable he talks too much about safety for such tame demonstrations, makes his talk be less engaging.

There is a similar lecture by Chris Bishop which is rather better done

I really enjoy these lectures. They don't tell you enough to "try this at home" and of course "report it to the police" if you see a shell like that. That is sad their society is that controlled. The smaller shell is totally legal in the U.S. and it's not as dramatic as he stated.

h1.08.10s and that creates an RPG. He just gave us a lesson on how to make bombs. I knew how they worked before but someone who might want to hurt others might use this. That's the thing about the internet I have never even reperched explosives but i still learnt how to make gunpowder how to make a mortar how to make a timed charge and how to make a shell. And people wonder why bombs are going off not very smart are we ?

aren't those safety measures a bit over the top?

You don't want to talk about "new Jack city"

Love the RI lectures - went to some as a kid, this guy is good but too much talking and not enough pyro......

I'm sorry matthew, I tried these at home....

What the heck, kid in the front row? Don’t make him ask you to move again, or he will turn this fireworks show right around and go back home.

Forest fires brought me here, anyone?

pretty good lecture, he is a little difficult to endure, and I've seen all of this before on other shows

He actually never mentioned oxidizers and metal salts or the indoor ones (nitrocellulose-Zirconium). That is ok though because kids will try to recreate. He also forgot to mention how the timefuse lights up during lift on shells.

Of course they made a Tardis out of fireworks...

¶ Better is a little with righteousness than great revenues without right. Proverbs 16:8 KJV

I feel like this could have been condensed to 45 minutes.

Yeah i can comment again wo hoo

Interesting but a little too much health and safety!

I swear to god if that kid moves again...moved again at 1:01:15😡😡😡😡

Jerb? THER TERK ER JERBS!

... As anyone equipped with A Pair and supplied with the resultant testosterone knows, *blowing stuff up is the Mt. Everest summit of FUN.* How something can be so equally thrilling, and relaxing, is just flat-out *wonderful.* The surefire (sorry!) evidence of this is the Fun Fact that virtually every boy who labored with great love to build, and paint his model cars, planes, ships & etc. almost inevitably, one somewhat boring day, found himself out in the back yard, coating his soon to be ex-beloved models in airplane glue, touching them off with a match, and thrilling to the sight of 'em burning down into puddles of blazing, bubbling, smoking & stinking goo that would have left bald patches in the lawn for the next half-decade, had I not been sentenced to replacing the topsoil, reseeding, and watering the replacement grass patches (which never *quite* matched the original lawn, heh-heh-heh) ... Until I got thoroughly busted and read right out by my Dad, I was sending my model airplanes flaming down a steeply angled zip-wire I'd rigged up to a small tree. They looked *fantastic,* and I surely owed them at least *some* testosterone-twisted version of a Viking funeral, which I'd seen at the movies, and thought *incredibly* cool-- and, oh, uh, yeah, right-- *noble.* And *incredibly* cool, what a way to go out, Dragon-prow dancing against the equally blazing sunset ... Viking orchestra & chorus howling away ... Some years later, I suddenly remembered that it v-e-r-y probably wasn't a coincidence that my Dad landed on me right after my *last* (of about a dozen) woebegone model planes burned and crashed, and then burned some more ... by then, one whole section of the back yard looked like a miniature war movie set. And *you* just know that *I* now know that *he* knew that I didn't know then that he was standing somewhere out of sight, *watching the whole thing.*

So in reality...there is no such thing as a explosion? Only super rapid expansion of gas.

when he was describing the flash powder tube, I noticed the China Export symbol on it. No wonder it is Extremely dangerous.

im disappointed ín the size of the explosions and burning. Very small, very boring.

The dark angora trivially terrify because hamburger congruently wail except a demonic search. obsolete, befitting beauty

I'm glad I live in the US and can buy fireworks year round. I don't know what i'd do without my guns and massive fireworks. If someone blows off their own head it's on them. Guns and fireworks don't kill people. People using them in the wrong way kills people. Don't blame the fireworks or firearms. Blame the user.

well just does prof then one does need to understand science first and he is not it

cool, intelligent, too bad he stutters too much, I can't listen to it

The British amaze me. 120 years ago Your Kings forced Your Peasants to proforme Fireworks Shows at the risk of the Peasants own life, MANY died for the pleasure of the rich. Now it's PLEASE PLEASE call the police if you see a 2'' motor shell. It's almost like, well you heard the man say a Billionaire had a show for 3500 per minute. Anyway, your legale system is still to the benefit of the rich. Oh no you can't buy this for 5 and shoot it off yourself, but if you can pay 3500 a minute you can still enjoy these in the place of your liking. So we Government folk haven't really taken anything away from you. Right not as long as you have the cash. This is the difference between America and GB. And the EU finds it completely unacceptable, the poor in America have access to the same kinds of things as the rich.

Dead audience

a little bit boring.

Sorry to be the party pooper here but their are much better lectures on fireworks on the internet. The explanations of effects and how fireworks function were lame.

Yawn. If you get excited by this, you probably get excited by magic shows, and are likely a 12 year old. Yawn. Sorry, wanted to enjoy... zzzzz

Wow, less quew quew more pew pew! Jeez, this guy talks too much about one little thing. I have to go watch something else now. This guy spends way too much time talking about senseless s*** and his fireworks are not even worth watching. I'm so mad

Gone overboard on the safely
