Researchers manipulate water waves for precise object movement

Researchers have developed a new technique to manipulate water waves, allowing them to move floating objects like ping pong balls and grains of rice with high precision. This method uses 3D-printed structures to generate specific wave patterns in a water tank. The study, published in February, demonstrates that these waves can hold objects in place or guide them along circular paths. The researchers found that small external waves had minimal impact on the movement of the objects. Future research may explore applications at both molecular and larger scales, such as controlling boats or cleaning up pollutants. The team also plans to investigate wave patterns beneath the water's surface.
