This paper demonstrates the manipulation of objects in disordered and dynamic media by optimally tailoring the momentum of sound waves iteratively in the far field. The method uses real-time scattering matrix measurements and a positional guide-star, without requiring knowledge of the object's properties or the medium's structure. Experiments show successful object movement and rotation in complex and dynamic scattering media, opening opportunities for biomedical applications, sensing, and manufacturing.
