If oxygen means fire, how do we get it on airplanes? #shorts #science #SciShow

The video explains how emergency oxygen masks on airplanes work without storing oxygen. Instead, they use chemical oxygen generators that produce oxygen on demand. The process is initiated by pulling the mask, which triggers a chemical reaction to generate oxygen. This reaction involves sodium chlorate decomposing into oxygen and other byproducts. The oxygen supply lasts about 30 minutes, sufficient for emergency descent and landing.
