The ocean is not a homogeneous body of water but contains density currents formed by variations in salinity and temperature, a layering phenomenon known as "immiscible seawater." Higher salinity water, being denser, sinks while lower salinity water rises, driving global ocean circulation. Our interactive exhibit "Immiscible Seawater" allows you to recreate this oceanic mystery with your own hands. The exhibit features dyed saline solutions of varying concentrations, temperature control devices, and observation equipment. Participants can select dyed saltwater and slowly pour it into the observation tank to create beautiful layers; by adjusting the temperature, they can observe convection caused by density changes; after breaking the layers with a stirring rod, they can use microscopic equipment to examine subtle changes at the interfaces. Each step vividly demonstrates how salinity gradients affect seawater movement and how temperature alters water density. WhatsAPP?+86 18882709667
