Abstract: The movement of liquid water droplets against the gravitational field has been shown. This was observed when projecting condensed steam droplets downwards. The observations show that the droplets decelerated and turned around at a point with their velocity becoming zero and begin moving upwards against the earth’s gravitational attraction. Further to the above observation, condensed steam droplets kept in an inverted container were examined. Some of these droplets showed upward drift while others drifted downward. The higher density of water droplets relative to surrounding air doesn’t satisfy the condition for the buoyancy to be responsible for the upward movement. The conditions required to create convection current were also not present at the region where droplets begin their upward movement. Therefore, no adequate explanation of this droplet movement against gravity can be given with conventional laws and hence a novel way of thinking is needed to explicate the behavior.
