i pour out water at the length of 3 meters, after a moment it divides into small drops, how
can i make it move only in one direction?

The reason this happens is because of air resistance. you can try to pour it out slower and hope that the surface tension of water will keep it from spraying out, but falling from 3 meters is pretty high. The air resistance basically "splits" apart the stream by breaking the surface tension. One way to do this is to give it a solid surface to run down, such as a pole as the other poster mentioned.
You can also try a string that starts at the source of water. This could also give the water something else to attach to as it's falling, and it is less likely to spray out, although i still think it will.

Once in free fall, surface tension with cause nonuniformities in the flow pattern to grow until the water to collects into globules and drops. To extend the range before this happens, the flow stream needs to be round, uniform, and steady. This can be created with a nozzle consisting of a simple straight tube. This will homogenize (smooth out) the flow before ejection. The optimal diameter for 3 m shot depends on water pressure. Experiment with different diameters. Start with 1/2 inch ID.

Get a 3 meter pole of some kind and pour the water so that it runs down the pole.
