Most of the atmosphere is made of Nitrogen (78%) Oxygen is 20.9 % of the atmosphere. Carbon-Dioxide comprises less than half of one percent of the Earth's atmosphere. 0.04 % to be exact.

Air Is Magnetic

Oxygen is Paramagnetic, this means it becomes magnetic when it is present in a magnetic field and attracted to it. All the other gases in the air, Nitrogen and Argon are Diamagnetic they become magnetic when they're in a magnetic field but are repelled by it.

The main component of air, nitrogen is slightly repelled by magnetic fields. But oxygen is attracted by Magnetic fields; all the gases in the air react to magnetic fields.

Super Batteries

In recent years, standard cylindrical battery makers have started putting lithium power cells into rechargeable AA and AAA batteries and have managed to increase their storage ability to a staggering 3000 milliamps (3 amp-hours). At the same time they still managed to cap the voltage at 1.2 without causing them to explode or burn, that is astonishing.

These things will literally last all day for normal uses. 

With clever circuitry, a single lithium AA battery can power a 50 inch TV  for long enough to watch a movie.

Umbilical Cord

Before you were born you grew a cord out of your belly called an Umbilical cord. It allowed you to live without eating or breathing throughout your time in the womb. 
The Umbilical cord comes from the fetus not the mother.
