With the use of simple wave generators, experts at the Australian National University, Canberra have demonstrated the idea of manipulating floating object in water. The same approach has also helped them in moving the object against the course of the waves. In order to display the phenomenon, the team placed a ping-pong ball in a tank containing water. Then three-dimensional waves were produced which in turn created patterns on the water surface and consequently, the ball stayed in one position or move towards or receded away from the wave generator…
