Funnels will divert rain drops to a liquid container present in the same tile. You can see the current amount of water funneled by xamining the container from time to time (check the Portions part).
In earlier versions you had to stay near the funnel for it to work, as many calculations are only performed within your reality bubble. This is no longer the case - now funnels will retroactively fill containers when you get near.
If the rain that is falling is acidic, it will either poison the water or turn the entire stack weakly acidic. The chance depends on how much water is already stored in the container. Water can also dilute pure acid water into weak acid water in the same way. Once a container contains weak acid water, no amount of neither water nor acid water will dilute or concentrate it back.
