To test some water techniques I got a glass, flat bottomed lasagna dish and filled it with some water. I attempted to light it but I don't have my own professional equipment. using the slo-mo setting on my phone, I moved the dish to get waves in the water. I then made some bubbles in the water and used a macro lens to get much closer to them.

At first I did it over a magazine (nearer the end of the video), then I used footage of the singer from the test shoot. It wouldn't be over the actual performance in the real thing, but those clips were the closest I could get to what we'd actually use which would be shots of the singer not lip-syncing, and being quite moody.
