In this experiment you can very graphically see the formation and flow of convection currents. You will need a jar of water, a film can and some food coloring. Add a few crystals of potassium permanganate pour hot water in the film can. Place the cover on the bottle. The lid has a central hole and also thread with which to lift it. 
Lift the film can of hot colored water with the thread and place it in the big jar of cold water. Soon you will see amazing convectional currents rising up. As hot water is slightly less dense so it raises us producing these marvelous currents. The whole thing looks like a volcanic eruption – red hot lava spewing out of a volcano. You can enjoy the top view. The colored hot water rises up like a plume and slowly gets diffused in the mass of cold water. These convection currents also look like a nuclear cloud. These dazzling currents are a splendid sight to behold. This work was supported by IUCAA and Tata Trust.
