Another 'riddle'.

Say you're drifting in a boat in a pool, and you have a large rock on board.
When you toss that rock overboard, into the water... will the water-level rise, drop or stay the same compared to the situation when the rock was still in the boat?
As ever, supporting calculations are most welcome

Well I am guessing that I have missed something obvious and I am getting this wrong but I will say... rise.

I'll go with Stay.

Logically speaking (unless I have misread the question) the level of water must rise...

The level of the water will remain the same as if it were in the boat, the weight of the rock displaces as much water in the boat as it does in the water.

I was thinking the same as Pitt, plus it's a riddle.

yeah I know it is.. that is why I am not sure about it.

Ok ok, I mis-titled it as a riddle. I's just a calculation Q. Sorry for the misunderstanding.

Anyhow, you are all wrong.

The solution is in the fact that rock has more mass then water.
So lets say you have a stone with a volume of 5 litres and a weight of 30 kilos (estimating) with you in the boat. While the rock is in the boat, it's weight forces the boat down, displacing 30 litres of water according to it's mass.
When you trow it overboard in to the water, the rock displaces water according to it's volume; 5 litres.
So when tossing the rock in the water, the waterlevel will drop as the influence of it's volume is lower compared to the influence of it's mass.
Seeing the picture?

Don't worry, most people get that one wrong

F*cking movies and their so-called historical correct content. Should have known....

Was it a certain spoken command?

You were closer first time.
