It was probably nitrous acid or dinitrogen trioxide that gave the distillate the blue color.

Great stuff! But hey ... don't wear the gasmask when putting speaker on your videos. Just voice over without it, it's not like you need to lip-sync now is it? :)

Wenn's nur für die Wissenschaft war, alles bestens. Ansonsten macht Natriumhydrogensulfat nen besseren Job und ich auch billiger.
