What does an overflow can do in science?

An overflow can is used in scientific experiments to measure the volume of an irregularly shaped object by determining the amount of water displaced when the object is submerged. It typically consists of a container with an outlet at a specific height, allowing excess water to flow out, ensuring that only the displaced volume is collected. This method is particularly useful in physics and engineering to calculate density and buoyancy properties of various materials. Additionally, overflow cans can aid in fluid dynamics studies by providing insights into liquid behavior and displacement.
