Always pour from a height.
Hold the container which contains the liquid approximately 10 cms high above the empty container into which you are pouring it.
Tilt it quickly
Tilt the container containing the liquid quickly when you start pouring it. This will prevent the liquid from dripping along it's sides.
Use a spoon as a guide, if required
Hold a long handled spoon vertically in the centre of the empty container into which you want to pour the liquid with one hand. Using the other hand, gently start pouring the liquid along the handle of the spoon, so that the liquid will slide down the handle and fill the empty container.
