So the burning green liquid I poured into this is essentially:
Methanol + boric acid.
Just mix them up. By a gentle condensation reaction, that makes trimethyl borate:
3CH3OH + H3BO <—> (CH3)3BO3 + 3H20
The methyl borate burns bright green (any methanol burning is colourless)

But for an extra “kick” (and because it bothers me there’s some water left over)…
… I also threw in some Copper(II) Chloride. That makes the solution green, but also adds its own blue-green colour to the flame - giving it a little more spooky anger. 👻
