I shot this using my Nikon D70s and Tamron 90mm macro lens. I used my SB800 for backlighting. ISO 200, f/11, 1/500s. I tied this glass to my son's toy (a bus) and rolled it on a table. When I gave a jerk to the setup, water splashed from the glass. I moved the setup with my left hand and fired remote with right. And yes, I placed this whole setup in my bath tub :)
