There is a pot full of water. How to pour out half of it without using a meter?

this is based on one assumption - that the pot should be made of glass and has some uniform shape...
the approach wud be to tilt the pot so that water pours out and when you see that the water level is seen to be diagonal on the alternate ends of the pot then it's half empty....
hope u've finally got the answer u've been looking for....
This sollution has a little bit less of an assumption I think. We need the pot to be translucent and to have a top. Fill it up and then pour out water until it looks about half full, mark the water level. Then turn it over. If the upside down water level does not hit the same spot then it is not half full. Change the amount of water slightly and try again. (I'm pretty sure this will work even in a strangly shaped container.
Incline the pot a little to pour water from this pot . Continue until the one corner of the water level just touches the bottom and the flowing out at the pot at the other end. The water level is just diagonal of the pot.
The turning upside down idea requires a plane of symmetry in the container. This is obvious when you consider a conical flask for example, an amount of water in the bottom will have a lower level than in the top!

No possible answer as pot shape is not given.
Just make 2 holes exactly opposite and keep the pot closed and such that the 2 holes are horizontal.
Assumption: the pot is symmetrical in shape.
I don't quite understand the question. Can I drink the water?
lol retard
