This mesmerizing reaction occurs due to Chemiluminescence, where luminol (C8H7N3O2) reacts with potassium ferricyanide ((K3Fe(CN)6) in the presence of sodium hydroxide (NaOH) and water. The ferricyanide acts as an oxidizing agent, exciting the luminol molecules, which then release energy in the form of visible blue-green light as they return to their ground state. This process mimics how fireflies and deep-sea bioluminescent organisms produce light. When observed in a flat glass under darkness,
