The soup with excessively salty level will cause health damage, also increase the probability of cardiovascular disease and high blood pressure. Therefore, the salty of soup is one of the key points to ensure our health. The design idea of buoyant salinity spoon is based on the mechanic of buoyancy. The higher the salty the greater buoyancy and the less salty the less buoyancy, thus we can measure the salty level of soup.
