Convection currents are found in many places and on many scales, from huge convection currents in the atmosphere, oceans, and even in the earth's interior to smaller convection ... The drawings should show the movement of the colored water (currents) and its relationship to the hot water or heat source for convection.

Superabsorbent polymer is well known to be capable of absorbing thousands of times its weight of water. Superabsorbent polymer gel is used here to exhibit a convection current of water by heating because with its high absorbent property the gel's density is almost equal to that of water.
