Measuring Buoyancy by Displacement
I am doing a project that you have to get 3 different
types of cans (1 cola, 1 diet cola, and a lemonade). Then you need
a big fish tank with water in there and then you drop the different
cans in and see if they sink or float. So I was wondering how do I
measure the buoyancy?
Take a smaller container and fill it totally with water and place it
on top of a pan. Place the can in the container, allowing for the
water to overflow. Measure the weight of the water that overflowed.
That weight is the buoyant force.
