This Demo demonstrates Archimedes' Principle which states that any
body submerged in fluid is acted on by an upward force. This is
known as buoyancy. The first step is too show the spring scale's
measurement simply holding the mass, and the top loading scale's
measurement holding the beaker with water in it. The second step
is to show the change after you put the mass in the water while
still holding it with the spring scale.
