An interesting documentary about Oxygen.

Isn't it interesting that if you light a match in an environment of pure oxygen you'll blow yourself to bits, and ditto for hydrogen;* but if you light a match under water (H2O) not a thing happens?

Colossians 1:17 And he is before all things, and by him all things consist.

No AV; if you light a match in a pure oxygen environment there will be no explosion. The only thing that will happen is the match will burn very brightly. As for a pure hydrogen environment; nothing will happen as hydrogen requires oxygen in order to burn.

Oxygen does not burn; it supports combustion.

Interesting!

Thank you, my friend, for that info!

I stand corrected.

Some of the worst industrial explosions were caused by large concentrations of dust in the air..even sugar dust will cause a big boom.

Indeed. Here in africa at my briquette factory we have experienced many such explosions.

Still not oxygen burning. Just very rapid combustion caused by the large surface to volume ratios of small flammable particulates. A match does not have that level of ratio so no explosion.

As you see not everything can be worked out with common sense.
We need oxygen to breath but we can't breath underwater even though there is more than enough oxygen there.

I didn't say it was oxygen burning..it was the dust in the air..I thought the article made that plain.

Sadly I get a "This video is private" notice and it will not play.

On a side note the dust from grain silos was known to be dangerous for many years in farm country. Dust plus just regular air (roughly 20% oxygen) can "explode".

It is not that we need oxygen to breath, it is that we need a particular form of oxygen to breath. Pure, molecular oxygen.

Something will happen, the match will go out.

Yup.
