In this remastered and optimized sample you hear water being poured into a glass. The water raises until it is almost full. You can hear it from the very beginning and the water is being poured in consistent speed. Since the glass is not completely full in the end you can hear another quick shot of water being added to complete the filling task.
The sample has been optimized since there have been a lot of background noises first but now it is crystal clear, just like the spring water from the recording. The sample can be pitched and speeded up/down to make it fit a specific audio or video montage.
