This is absolutely amazing as every TED-Ed lesson. This is how teaching should be! :) However, I believe the elephant-gym example can confuse students, as the air pressure in an actual room is atmospheric pressure, so it is like having 10 tons (two elephants) each single square meter. Although it might be a difficult concept for educational videos, I think we should try to explain students that pressure is not about weight, but about molecular density and velocity. Anyway, awesome video: )

Efficiency of aniroid barometer is what?
If we know how efficiency of barometer going to change as its size increased in three dimensional ways i e bigger modal of barometer provides more atmospheric pressure and we turned a turbine with help of it?
So whole universe scientist are welcome to made a bigger modal of barometer Aniroid barometer so we get rid of energy crisis forever

Hmm. So you say air is a liquid. With that typem of phisology I could say that steam is a liquid as well. It's not, it is a false claim. It's gas. Gas Liquid. That's all

Who breathe heavily when she said there are more air molecules than the both numbers of stars in the universe and grains of sand in deserts in beaches?

It's pretty damn heavy. I was trying to get up off the sofa after my supper snack last night and the air kept pushing me back down.
