What If Oxygen VANISHED For 10 Seconds?

Your eardrums would rupture before your brain registered anything was wrong. That's what happens in the first second. Here's the rest. 10 seconds without oxygen sounds survivable. It isn't. In those 10 seconds: every jet engine dies, the global power grid collapses, exposed metal begins cold-welding itself shut, and the ozone layer takes damage that won't heal for decades. And most people — alive, buildings still standing — would exhale and think it was over. It is not over. This video walks through every second of a world without oxygen — and ends on a number so ordinary, most people never think about it twice. #WhatIf #Science #ScienceExplained
