I assume you are attempting to create moon water?
This is where you allow some of the moons energy to enter water, charging it, you can then go on to use in spells and rituals. I know many people do not use charged waters, or believe them to be nonsense, but I personally very much enjoy using them (even if it only for the placebo of having something you believe is charged by the moon).
For charging by the moon, it is a common practice to place items under (reasonably) unobstructed moonlight for a period of time in order to cleanse or charge them (depending on purpose). If this is what you were hoping then it appears that you have done it well.
