Imagine that you're sitting on a boat, floating in the water, and holding a rock that you then throw into the water, and it sinks.
Did you just cause the water level to rise, fall, or stay the same?
I want you to think on that for a minute.
And to make the problem a little more clear, imagine the boat is in a container not much bigger than the boat.
Will the water level rise, fall, or stay the same?
I recommend pausing the video to try to figure it out first.
Ooh.
So it was on my boat.
It, um-- And then I threw it in the water.
You would say that it would rise.
