I mean, they were first used in festivals in China, and, similarly, they're usually used in celebrations today. Feels like they're pretty divorced from anything related to war.

Thats actually a nice way of thinking about it

It does signify our winning of a war...

Indeed

It depends on the country, in most of Europe we light fireworks with newyear, depending on the country there's big shows and/or consumer fireworks. Personally I'm a fan of consumer fireworks (but always use it safely), I get the excitement and the uniqueness this man is talking about, even if I am just sitting around with a few flowerbeds and singleshots and he's programming an entire show.

4000 is sounds alot, over how many years is that?

Karl Singh I understood nothing😐

thats not Detail.. thats Basics

@@sp3z197 Karl was being sarcastic LOL

@@BriteRoy how would you know tho?

Zeus Modi your teacher probably is not passionate.

They teach it in UK, it’s required for GCSE’s. All about identifying ions, such as flame tests for metals, lithium - Crimson , Potassium - lilac, Sodium - Yellow, Carbon - Green, Calcium - Orange/Red (Brick red) Also the metal ions by precipitation reactions, magnesium, aluminium (which redesolves with sodium hydroxide to make a clear mixture again)and calcium make white. Iron (II) is green, Iron (III) is Brown, Copper (II) is blue and Copper (III) is brown.

I guess it depends on the school and their budget. I know that my high school chem teacher did a mini version of this with different chemical solutions and a Bunsen burner.

In the usa with post 9/11 views your gonna have a funtime trying to get permission to teach how explosive chemicals react with each other in a uncontrollable way.

Then you would know that Barium and Strontium are very Toxic Metals

Awwww lmao

Well, that could be possible.

I'm impressed by how stupid and yet pretty smart for a kid you are. LOL

@@Xperian13 haha.

Mee to

Quincy Murdoc I was thinking the exact same thing!

To you too, Alejandra Perez and Alyssa Rice! Thanks for watching

you too!!

America last

happy fourth !

Steven Scott whistles are made by pressing a tube with what's known as "whistle mix". Usually it consist of 7 parts potassium perchlorate 3 parts sodium benzoate. 2 parts iron oxide as a burn rate catalyst. The tube usually has an inch or so of empty space before the fuel grain starts , this causes a resonance "vibrating" effect much like a whistle, due to the fuel burning so violently. This in turn causes the whistling effect. Crackle, also known as dragon eggs are a bit harder to explain. But it usually consist of an oxidizer, nitrocellulose, powdered magnesium-aluminum alloy, and bismuth trioxide. The popping effect is caused by the rapid cooling and heating of the pyrotechnic material, the effect happens when the compound is heated so rapidly it actually makes a popping sound, Combine this with multiple other crackle "stars" which is the compressed, granulated pyrotechnic composition you get the crackling effect. Hope this explains some things for you! I know this because I am a licensed display operator, and manufacturer of fireworks, as well as a hobbyist. I also happen to be in this video!

@@pyrotom8139 here's a less obvious much more difficult question. How come no one ever captures accurately THE SOUND of fireworks in recordings? I have only seen 1 like no kidding literally JUST ONE video on youtube that actually captured the bass and low frequency oomph produced by loud salutes in a finale. I have been searching for about a year now for a camcorder or anything really that can ACCURATELY record the audio of a fireworks show and I have failed with every attempt.

@@yamafanboy where are the microphones positioned .... Thats just a guesstimate

well my condolences to you for the outcome of the As game this evening ;p they looking pretty good though, but no team looks as good as fireworks!!

Neil Hatrick Harris I missed the game tonight, and I'm a Giants fans anywaysy freind just gets free tickets to A's games. But then again not like the Giants are doing too much better this season.

yeah lmao but hey, getting free tickets to games, thats pretty sweet!

Neil Hatrick Harris Definitely!

30 mins of fireworks is pointless and boring. Even the most expensive elaborate fireworks show can be dispensed with in under 6 minutes and have maximum impact and 100% audience satisfaction. I don't know why people stretch fireworks displays out to 30 mins that's dumb.

@@yamafanboy because a 30 minute shows gonna cost around $30,000-40,000. Gotta keep the clients happy. I worked this show for the Oakland A's. Started crew shows in the Bay Area around 1996.

Ever heard of Virtual Machines?

You mean your cousin...?

@@84knucks05 yea sry english isnt my first language

@@lahecoq2417 no need to apologize... i was trolling

Yes, there are some effects (such as horsetails or falling leaves) that make little to no sound. But many people enjoy the sound as much as the sight. Salute shells are a common firework in professional shows that create very little light or color, and are all about the bang

Take down your OL vids and I'll tell you.
