ANU Scientists create a Tractor Beam on water

Physicists at The Australian National University (ANU) have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The team, led by Dr Horst Punzmann, discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. The team also experimented with different shaped plungers to generate different swirling flow patterns. The surprisingly simple techni
