Cartesian diver 浮沉子

Cartesian DiverThe Cartesian diver is a classic scientific toy that demonstrates the principles of buoyancy and pressure, making it an excellent educational tool for teaching science concepts.PrinciplesThe Cartesian diver operates based on Archimedes' principle and Pascal's principle:Archimedes' Principle: An object immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.Pascal's Principle: A change in pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid.How It WorksWhen the Cartesian diver is placed in a large container of water, it floats on the surface due to the air inside it.Squeezing the large container (such as a plastic bottle) increases the pressure inside the bottle. According to Pascal's principle, this pressure is transmitted to the water and then to the diver.The increased pressure compresses the air inside the diver, reducing its volume and increasing its density.When the diver&#39
