The slightly magnetic qualities of liquid oxygen is very interesting. Also, as necessary as oxygen is to like, too much can be dangerous. Breathing oxygen at 5 atmospheres or higher pressure can be fatal. You get the same results breathing pure oxygen at normal atmospheric pressure. Normal air is 1/5 oxygen so pure oxygen at normal pressure would provide the equivalent of 5 atmospheres worth of oxygen.

Oxygen is very important to life but the atmosphere has been 20.9% for the 30 years I have measured it.OSHA Has set it up like this. 19.5 % is the lower limit about .2 below this u will go unconscious. at 21.5% is normal high limit.at 23% most things will burn like gasoline is on it. Now think of the earth as it is our spaceship traveling through space on a very long trip. Do u think we will be in trouble?? Wrong again even considering all the compounds of oxygen it level does not change because of a special system that protects us. Our upper atmosphere has a radiation shield of O3. but if the shield gets thin something special happens, Alpha particles will break through and bombard nitrogen with alpha particles which will trans mutate to O3.Isn't that wonderful how the system works.

By an interesting coincidence of nature, liquid oxygen has a sky blue color. It is important to note however, that the two phenomena are totally unrelated (the blue of sky is due to Rayleigh scattering and would be present even if there was no oxygen in air).
Oxygen is the most common element on Earth, and the second most common element in Earth's atmosphere (second to nitrogen). It composes around 49% of the mass of Earth's crust[1] and 28% of the mass of Earth as a whole, and is the third most common element in the universe. On Earth, it is usually covalently or ionically bonded to other elements.

Actually, oxygen itself will not explode, absent another fuel. One fact that may not be in the lower level texts is that the oxygen level was higher in dinosaur time, and differing oxygen levels have influenced what plants and animals have evolved.

When oxygen is cooled to its vaporization point and becomes a liquid, it has paramagnetic qualities. In other words, liquid oxygen responds to magnetism. It is a pale blue liquid that is attracted to a magnet that is brought near. It is the coolest thing to see!

Oxygen is one of the few gasses being (para-)magnetic
