Water Level Challenge
There’s a toy boat floating in a pool. Place a lead ball
in the boat (without sinking it), and measure the level of
water in the pool. Now take the ball out of the toy boat and
drop it into the pool, and measure the water’s level again.
Will the two water level measurements be different, if so
which will be higher?
Yes the water level will differ.
Boat carrying lead will rise water to level equal to its density and without lead it will have lower level.
So boat with lead will have higher water level.
