Take a clean and dry beaker and find it's mass (m) using a physical balance. Now find the weight of a stone by suspending it from a spring balance. Fill an Eureka can (Eureka can is a beaker having a spout near the top) with water filled till the spout. Place the beaker of mass 'm' under the spout. Gently lower the solid, suspended from spring balance, into the Eureka can, till the stone is completely immersed in water. When the stone is immersed in water it displaces a certain amount of water. The spring balance records lesser value thereby showing that the solid experiences an upthrust. The displaced water is collected in the beaker. Using the physical balance the mass of the water and beaker is determined. Let it be m₁.

∴ Amount of water displaced = m₁ – m

If we compare the apparent loss of weight of the solid in water, with the amount of water displaced, it is found that they are equal. This experiment thus verifies Archimedes' Principle.
