Rene Descartes invented the Cartesian Diver, which is an object that floats but sinks when pressure is applied. Rene Descartes created a way to demonstrate the idea of buoyancy and the ideal gas law. The name of the Cartesian diver came from the inventor Rene Descartes. Some objects float in water because of the difference in density of the water. Water is much denser than air, which means when the eyedropper begins to suck in water, the density becomes greater then its overall surroundings. Density is a characteristic property of a substance. Density can be increased by increasing pressure and by lowering the temperature. Pressure is a measure of the force applied over a unit area. The relationship between pressure and volume for a gas sample
