How To Make Green Fire With Household Chemicals

Whenever conducting chemistry experiments one should always make sure to use proper safety procedures and equipment such as (but not necessarily limited to) adequate ventilation, eye & skin protection, awareness of and adherence to any relevant governmental regulations and, if one is a minor, close parental supervision.

("v" indicates following number is subscript)
Hv3BOv3 (boric acid) + 3CHv3OH (methanol) ----} B(OCHv3)v3 (trimethyl borate) + 3Hv2O (water)

It is the trimethyl borate fumes that are burning green (along with any left over methanol which burns a less visible blue).

While relatively safe to handle, trimethyl borate is a gas that can irritate eyes, skin and respiratory systems, is invisible, obviously flammable, somewhat explosive in high concentrations and is heavier than air (it flows downhill and pools at the lowest point it can reach).

H3BO3 -> HBO, Producer of Game of Thrones where they use a liquid called "Wildfire" which also burns with a green flame. #mindblown

Is the methanol part of the reaction or is it just used to combust the boric Acid?

So Green NOS flames in car games are made out of H3BO3.
