Thank you! Yes, the flames look almost like a CGI effect. Difficult to believe until you see them.
I agree, this is not new but by far the very best way to demonstrate it, have never seen it presented this cool!
This may work, but not tested yet:
If you have a strong bunsenburner or better a glassblowers torch you can heat glass in the flame to get a lot of sodium light. Put a shade between the torch and your alcohol fire with salt and a white screen behind both.

What makes the difference for the desired effect? The wave length?
Only low pressure lamps emit the narrow line spectrum that can also be absorbed and results in the „black flame effect“.
In high pressure lamps the Na atoms interact forming bands which results in a broadening of the lines and eventually a more or less continuous spectrum. Check it, most street lights (especially on city highways) these days are Na high pressure. You don’t get black flames.
