Answer 1

Get a water hose (clear poly is easier to read but not necessary), fill it up. Stretch it all the way out holding the ends up so no water spills out. The water level at both ends of the hose will be at the exact same height. As long as you dont spill any, the different ends can be moved to any distance possible and will still be at the same level. The water is leveled inside the tube by gravity.
