It is not clear to me exactly what you are wanting, but I will briefly describe one thing I have done. Use a piece of clear glass, and prep it with windshield treatment that makes water bead up to get larger drops. Support the glass horizontally so that you can put objects under it. Choose something interesting as your subject, like a flower or other colorful thing, and put it under the glass a few inches below. Then spray on some water to get many droplets that are beaded up. The size and number of drops is a factor, and you want middle sized or large drops. Try different spray bottles until you get one that does what you want. Each droplet should have an image of your subject showing in the drop, with each image formed by each drop that kind of acts like a fisheye lens. Experiment with how far under the glass your subject is, and with lighting angles and camera position, then shoot the drops as a macro, to show lots and lots of images of your subject. It is usually best to shoot at a slight angle to the glass, and not directly perpendicular to it, to avoid reflections. Also avoid light hitting the top of the glass, and direct the light only at your subject and its background, again to avoid reflections in the glass. You can also experiment with the background under the subject, and consider it being a color rather than black. You can also try multiple subjects, which show up as multiple subjects in each drop.
If that is not what you are trying to do, please explain fully what you want. If you are trying to freeze water drop motion, that is a whole other subject, and the key to short flash durations is to use manual power mode on a speed light, and set it to very low power, which gives very short flash durations. Then as mentioned, remove or control ambient light so that the flash is the only light on the moving subject.
