Sound something makes while travelling through a liquid [closed]

Solution 1:

swish vb 1. to move with or make or cause to move with or make a whistling or hissing sound

swish sound of an object moving through air or water

Examples from books:

After much though and inspired by the discussion on this page, the best word that I was able to find was "slosh".
