Great idea, but the battery is fuzzy and the hands are cropped. Keep trying, with a faster shutter speed or a flash, and you'll get better results. Try to get both your hands in the picture and maybe wear something black for the background.
I'm afraid, but I cannot reaaly appreciate it since it seems more a falling battery than a floating one (IMO). Furthermore the idea is damaged by the fact that the focus is not on the battery.
Neat idea. What could make the picture better is removing all the distracting elements in the background (belt, multicoloured clothes, lint, etc.) as well as capturing the battery in focus.
