how to make ROV tether/umbilical neutrally buoyant?

once you build the tether, use the foam ball things from walmart. Drill a hole all the way through, and then make a slice halfway through. ziptie the balls on

. If it floats, attach small weights. . If it sinks, attach small "balloons." . Best bet is to choose a cable that is inherently NB.
