English term or phrase: weighting
Begin by weighting the pen top so that it floats vertically just below the surface of the water. To do this, add sticky tack to the base of the pen top, a little at a time, pushing some inside to reduce the air content and buoyancy. Test in the bottle or a glass of water, and if the pen top sinks, simply remove some sticky tack.
