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?

Solution :

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.
