Firework colours and Electron Excitation

A visual explanation of how we get different colours from heating some of the metals commonly found in fireworks.

love that they give examples in what the compounds are used in

[@little.animals]

I did this at school for bonfire night and it was the funnest thing ever!

[@strenghkey8]

This channel is awesome, thanks for great quality in information and presentation👍

Thank you

Can you soak these metals onto a candle wick overnight and then make candles and have the candle flame burn these colours!?

[@BeatriceKenley]

Wow

[@iacovcoc4031]

Thanks

[@jamvously7170]

nice

[@denaroraflames]

Try Denarora Flame Color Changing Packets to get a colorful fire🌈🔥

[@nyakechmayom2588]

Thanks for information ☺️

[@jeremiatereima3288]

why do you need chloride in each element?

[@changminbbluvs4933]

Edi wow

[@Atrians]

why barium chloride is not green?

[@jpslmrn]

Gee golly!

[@user-zd2sy9sm2u]

温度需要达到2500 摄氏度以上，才能燃烧出真实的色彩，用铝热反应试试😅😅😅

What would be the control variable in this experiment?

[@kelzbeats4094]

yes

[@josiahscott4592]

factors that remain the same throughout the experiment

[@Hamza-B3]

Solid salts work best; you can dip platinum/nichrome wire in acid then to solid salt and burn it. Also, isnt barium supposed to be green?

[@Anglesandacid]

Thanks for the tips! I've just used what the school has on hand, but always had a suspicion that it would be easier to use the solid salts. The acid dip is a fantastic idea to clean in-between uses. Barium never seems to come up green/yellow for me so perhaps there's some contamination going on. Thanks again for sharing!

[@ls13355]

Barium salts gives a light green colour to the flame. Solid salts taken on a tiny loop of metal wire will give best result

[@user-rl5mt2lp6f]

Barium gives us a pale green or light green color and not " a very orange yellow "

[@BPSScienceTeach]

I noticed this too. Barium should be green.

[@abdimohamed8926]

A fun fact I learned today is, fireworks are made out of hot embers of metals.

[@introvert6T9]

u should have used cotton buds instead
for detailed vision

[@Anglesandacid]

That's not a bad idea, I might try that next time :) There's always a risk of the matchwood or cotton bud catching fire and affecting the colour, so I think the best results come from using a metal spatula with the powder instead.

Uranium 😁

[@josephnaylor]

no lithium ?? :(((( its so perrtyyyyy

[@MadScientist267]

Go thru all that to demo the colors...
And use *wood*... 🙄

[@mishkat4291]

Some of the colors are really wrong 🤣
