You know O2 is pure oxygen right? Unless we’re getting into the technicality of if things in there gaseous forms can be licked it’s safe.

i think gasses can be licked, for example - if i put menthol shards into hot cup of water, i can definitely feel it on my tongue if i lick the air above the cup. therefore, lickable

Get a bottle of pure oxygen and open it over a tongue-simulator¹ to see what happens.

People usually use a hot-dog. But with oxygen, even a piece of wood is close enough.

  You need something else along with the oxygen to cause combustion.

  The mercury and Gemini space programs had cabins consisting of pure oxygen. And those astronauts were fine.
