Odd bit that.  Ice displaces it's weight in water.  If you have a gallon
bucket and a quart of ice and you make a mark on the bucket where the top of
the water is before putting the ice in the water.  Be sure to make the mark
on the bucket, not on the water or the eis.  Now put the quart of ice in the
water and mark again how high the water is (on the bucket).  You will note
that it rose about that amount that is close to 0.9 quarts.  Or roughly 22%.
If you do the same with a quart of lead the water will rise fully one quarts
worth.  Or if you add a quart of liquid ice it will rise one quarts worth.

Now here is the test.  If you venture out upon a still lake with a vanagon
transmission in your boat and mark where the water is on the side of the
boat.  Then put the transmission into the lake.  which way does the water go
on the side of the boat, up or down or does it stay the same?  And by
approximately how much?

Eureka!
