In order for gravity to work, you need a source of GRAVITY.
I'm..I'm speechless. this...this isn't even...dangit man WHAT WERE YOU THINKING WHEN YOU TYPED THIS?!? sorry...sorry. I mean, all caps, bad form, I know but, seeing this typed out. just...wow.
I mean, is it in your mind set that gravity is somehow not effecting the IV bag? Like that line about there needing to be a hole in the bag TO LET THE GRAVITY IN? (That quote, for those of you just tuning in, was
)malcolm kirkman said:No BIG hole in the top of the bag = no chance for GRAVITY to act = the photo is staged.
But none the less, I'm gonna help you. My guess is you're confused about Air Pressure, not gravity. It's moot in the case of IV bags, because they collapse as the liquid drains out. Also, it's not how high above the ground the IV bag is - it only has to be higher than the patient.
Anyway, that was not pole number 2 in the previously referenced photographs, and you can't seal gravity out of a bag by closing it.
