If the density of a substance is more than the other, it sinks. If its density is less, it floats. But rice is a solid,and not a fluid. Can things sink and float in rice?
By adding energy through the electrically or mechanically manipulated vibrations into the container of rice, we can make it behave like a fluid. Once the container starts vibrating, individual particles of rice acquire energy and start getting displaced. Mild vibrations make sure that the particles are constantly moving so that they cannot collectively produce the normal force that static rice particles can, thus exhibiting fluid-like behaviour. A metal ball is therefore denser than a container of rice, which means it sinks. On the other hand, a hollow plastic TT ball is less dense, which results in it floating to the surface.)

d’Art of Science partners with DFC 2017
Starting this year, d’Art of Science partners with DFC for promoting Hands-on/DIY Culture in Schools by starting a sub-award in the annual DFC Challenge. One school selected under the Best Prototype Award will get a chance to travel to Goa and develop their solution prototype in Goa with us. Over… READ MORE…
