China pot

China pot
This is a magical ancient Chinese pot, As you look it, it has not a cover, then, how water is going in?
Secret in the pot's Bottom! In the bottom, there's a tube, straight through to the top of the pot, the water is from here.
So, when adding water, will not leak from the spout it? will not!
Because the spout has another tube to extend along the kettle side of the pot, only the water diffuse through the nozzle, will be out of water.
Fill the water upside down, no water out.
