Nozzle for plastic bottle under the tube / Насадка для пластиковой бутылки под трубку

Sometimes it's necessary to quietly pour water from a bottle into a specific spot, like a flower tray if it needs less watering. To do this, simply attach the tube from the aquarium pump onto the modernized lid (5mm landing diameter) and you can fill it where needed. If tightened properly, no leaks occur.
