▼ So you use fire inside the chemistry lab?

 Yes, we finding if the fire burns is because the oxygen exists.

Like you are breathing.

(red) So if the fire near me, in the lab, they gonna explode on me? 

When you use a match, inflame something or the chemistry lab they have this burner, they use to ignite the flames, its like you light up a candle, do you feel the candle will explode on or next by your face?

I thought they are using something special in the lab.

No.Its a tool to continue supply the oxygen in a steady methods, so that tool is to heat up the solution to a particular temperature.

Does your climate change video, a chemist will be working on the climate change?

In NASA, they work on everything, so will their scientists if they are coming from the natural science degree like a chemistry, physics, or biology....

(Red face) Do you talk about the oxygen there and here, in the candle, in the lab the same oxygen?

Because we are living on Earth, its air everywhere, with the air exist everywhere, you don't vaccum flying in space without gravity. Yes, the same oxygen. The same air, you walk everywhere on Earth.

Air on Earth all the same?

Yes, or else you will die by walking 2 feets away every few blocks.

(Red face) Is that because oxygen is everywhere?

Yes ! 

Because Earth gravitate the Oxygen?

Right, you live on Earth.
