The farmer is often necessary to pour different liquids (fuel, water, and more) from large vessels. Alone to do not. I propose a simple device that allows you to empty any container up to heavy tanks. And without tipping over. Moreover, there is the ability to quickly and carefully drain any liquid, even when the receiving tank is located on a small hill.
The device is a plug (wooden or rubber) with two openings: one with a diameter of 10-12 mm, and the other 18-20 mm. is inserted Into the holes of the tube — a plastic or metal. Tube of larger diameter reaches almost to the bottom discharge tanks capacity.
