Demo for archimedes principle

[Necm]

Homework Statement

Hi, in my high school physics class we have to teach (part of) a lesson, mine being archimedes principle, and we have to make a demonstration of our topic. My idea was to show how you can calculate the buoyant force on a immersed object with the weight of the water it displaces, but my teacher said our idea was rudimentary and we should try and think of another idea, but i have no more ideas. Is there anything better i can demonstrate to a class about archimedes principle? Thanks!

To demonstrate a principle, the most direct and simplest method is the best. How would you perform the experiment in detail? What tools do you need?
