The video tutorial describes an experiment where nitrogen in the air is oxidized using an electric arc. The setup involves high voltage and a gas wash bottle to prevent air entry. Formic acid is used due to its presence in space. After one hour, the heating mantle and condenser are activated. The experiment runs for 24 hours, after which a sample is tested for amino acids using the anhydrin test, showing a color change known as Ruhemann's purple. A cross-test is conducted to confirm the gas source. The video concludes with open questions about the experiment's reproducibility and reaction mechanisms.
