Abstract
We propose that by using the concept of negative mass, the dynamics of objects embedded in fluids can be considerably simplified. For example, helium balloons, whose motion can be puzzling in a non-inertial reference frame, can be easily explained using the concept of negative mass. Two experiments have been carried out to demonstrate this idea. The same conceptual idea can serve as a model for other circumstances, when it is simpler to focus our attention on the lack of matter rather than on its presence.
