A closer look
Oxygen transitions from a colorless gas into a pale, beautiful blue liquid when it is cooled to incredibly frigid temperatures below minus 183 degrees Celsius. This beautiful coloration is due to the way oxygen molecules absorb red light and reflect blue light, a property that becomes visible only in its dense, liquid state. Of course, this stunning liquid is also highly reactive and will violently accelerate the combustion of almost any material it touches. It is a classic move by the universe to make one of the most dangerously explosive substances look like a refreshing, artisanal blueberry sports drink. Scientists use this azure fluid to launch massive rockets into space, bravely ignoring the fact that it is basically angry blue Kool-Aid ready to incinerate anything that looks at it wrong. Chemistry is essentially just physics with trust issues!
