The Science of Pyrotechnic Effects – with Matthew Tosh

Too excitable - I have a headache now!

Andrew Szydlo needs to show this guy how its done

`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.

Great job !

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

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

Very good presentation by Matthew with loads of information.

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

Interesting but a little too much health and 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!!!

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.

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

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.

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

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

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.

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

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!

Interesting video. Pyrotechnics are always fun.

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

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.

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.

SMILE.

Woke up to this playing. Watched the rest and subbed

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

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

Forest fires brought me here, anyone?

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

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 ?

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.

Dead audience

no wonder he is an expert

each time he talks, the words are exploding 🤣🤣🤣

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

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.

a little bit boring.

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.

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 wish we could get some lectures aimed at adults

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

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

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

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

Brilliant. Totally engrossed and enlightened !!

Gone overboard on the safely
