LOVED this video! Was like Deja Vu! I went through all of this about 5 years ago when I started making my own fireworks and rocket engines! From homemade black powder to r-candy, right down to flying FPV quadcopters through fireworks! My favorite pyrotechnic mix is currently sulfur-zinc flash powder! MUCH easier to make and is non-hydroscopic so easier to store as well! You can also change the deflagration rate! I currently use it to make projectiles for my homemade rocket launcher! Come try it sometime! ;-)

Derek's storytelling is insane right now. From start and end from the same evil spirit's line. Just the perfect way to join multiple footages, different locations and topics woven together as a complete story. To take the explanation parts and seamlessly transitions to practical demonstration, fun, self exploration. From teaching us and being taught and the constant voiceover during it. JUST LOVED IT. this must be my favorite video of yours's in every aspects.

The reason why copper can produce green and blue colors depending on the environment is that copper ions can exist as cuprous (Cu+) and cupric ions (Cu2+). Cuprous ions produce blue flame color, while cupric ions produce a green one in the presence of halide ions. When a flame contains reducing agents in excess (e.g. candle flame or burning alcohol), then the cupric ions get reduced to Cu+, so the flame will turn from green to blue. As the cuprous salts are generally not stable, blue fireworks usually contain Cu2+ salts and the rest of the mixture is made to have a strong reducing environment (fuel excess), so the cuprous ions are formed in situ during the combustion.

11:50 In middle school, my parents allowed my friends and I load artillery shell fireworks during 4th of July.
One of my friends loaded the shell in upsidedown by accident. Instead of the THUMP sound you hear when it gets launched into the air, we heard a little PoP, and saw a foundation of sparks pouring out of the mortar.
I knew right away what had happened ๐ฎ and I yelled, "RRRRUNN!!!"
We all scattered as fast as we could. When it exploded, it felt like a major league pitcher threw a handful of hot sand and rice at your back.
No one got hurt, thank goodness.

I've always loved fireworks.
Just watched this video midday today (Sat, 26Aug2023).
In my town, when the local baseball team wins a home game, they set off a fireworks display, which can be observed from many locations, whether one was present for the game or not.
Our team won tonight, and this video allowed me to appreciate the show in brand new ways!
Great job, Derrick, and all you (and all of you) have created with Veritasium! Kudos, and please keep it up!
