Water Beam

Physicists hailing from The Australian National University (ANU) have created a tractor beam on water that could confine oil spills and manipulate floating objects. The results of the experiment published in the journal Nature Physics states that anyone in a bathtub can reproduce it.

Physicists used a ping-pong ball in a wave tank after which they worked out the size and frequency of the waves required to move the ball in whichever direction they want. It was revealed that the waves generated currents on the surface of the water.

Researchers found that above a certain height, these complex three-dimensional waves generated flow patterns on the surface of the water; one of these pattern was the tractor beam. The team also experimented with different shaped plungers to generate different swirling flow patterns.

The most wonderful and precious element of universe is the human life which can only be guided by the right knowledge and right attitude. So, here is an ocean of knowledge, both in English and Hindi encompassing every detail and each facet of human life which ‘one must know’ in order to grow and attain the summits of success. A team of around 200 dedicated members is working ceaselessly to turn such a colossal dream into reality. We are confident that this portal will help bring change in people across the world.
