Can't be accurate. Pure O2???

Actually welding oxygen is held to a higher standard than medical oxygen and is very very close to being pure 0²

What is marketed as pure ethanol, "Everclear", is really only 95% pure, alcohol has an affinity for water.
The 100% stuff is called "absolute alcohol"

Yeah, we have some absolute alcohol (100%)in the lab I work in. Nondenatured, to boot. It's funny when you read the label. Just like any chemical, it has warnings if you ingest it. Target organs : liver, etc. Also says "may effect behavior."

The water/alcohol mixture has a depressed boiling point that results in the 95% limit. To get to 100% you add benzene to the alcohol. That takes the last 5% of the water away, but makes the end product toxic for human consumption.

IIRC, my HS biology teacher told us pure alcohol was pure poison.

Isn't ether the gaseous form of alcohol?
