In the meantime, Question of the day:
Thomas is in his rowboat, about to lower a solid bronze mermaid into his pool. Once this sculpture is placed on her throne successfully, will the water in the pool have risen, fallen, or stayed the same level as shown below?
Bonus: Will the water level rise, fall, or stay the same when the mermaid is fully submerged but has not yet touched the bottom?

I would suggest eclipses because this year was very special and Prophetic...This year a week on either side of the Equinox was BOTH a lunar AND sloar eclipse which is mentioned in prophecy to signify the coming of a prophet to be recognized in his 40th year.
THIS is my 40th year by some coincidence.
Well, as I always say;
"I don't think I know..I just know I'm thinking."

Interesting.
Have any of you actually seen an eclipse before?
I have a vague remembrance that when I was little, I saw one at school (when I was in Canada) and our teachers told us not to look at the event directly.

we've had this type of Q before in f4 with cass. that time it was like someone wanting to raise the level of the boat and so he threw his dog overboard.
my answer: level will drop. the original displacement by weight is greater than displacement by volume. now i think about it, the dog might not be heavy enough. oh well.
ps. stop being so negative about the mpi.

eco11,
very good; you may try the bonus

it has nothing to do with heaviness; it's the relative density that's important here

I'm not being negative about the mpi... just being cautious,

density is mass/volume. obviously the dog's volume remains unchanged. so when i say it isn't heavy enough, means mass isn't big enough => lower density. dot dot dot, therefore, your statement above does not hold. heaviness and density are related in this case.
can't believe even on your blog i'm arguing with you, lol. so impolite of me.
like the special effects. teach me some day.

eco11,
do I get what you are talking about? not really?! The dog was probably also made out of bronze... lol

thanks, there's not much to teach; I just used an imaging programme.

ANSWER to Question of the Day:
The water level will fall.
When in the boat the mermaid pushes the boat down (thereby raising the water up around the boat) by an amount equal to the weight of the object. Once on the bottom and not attached to the boat, the mermaid will only cause the water to rise by an amount equal to the volume of water displaced. Bronze is extremely dense, so the weight of the sculpture displaces more water than the volume.
***
BONUS answer: The water level will not change until the mermaid touches the bottom and the pressure on the rope is released.
