I just watched the walter lewin lecture on fluids, and he had an experiment where he was sucking it out of a hose when the hose was in a U-shape, and he was only able to bring the level up about a meter. However, when he got on a ladder and was sucking out the juice from the floor in the container, there wasn't any trouble sucking it out 5 meters
Somehow him being on the ladder 5 meters up is the reason for this, and I can't figure out how this works.
For the 2nd experiment, he was sucking the air out of the hose creating a vacuum, so the air pressure at the bottom of the container was pushing the liquid up. But, I would think the same principle would apply for the one at ground level, yet it didnt.
