To use, simply fill the cup with water, put on the lid tightly to create a closed space in the cup and turn the base towards the right until the three holes (water outlet) correspond with the spout at the base of the cup. Now, let the water be guided gently through the spout. When the user presses the lid, the air gets into the cup through small holes, releasing more water.
