Ice in swimming pool.....say what? It's turning

For the past few days it's been a case of "say what"?
The swimming pool is round and freezes into a solid 4ft high/24ft round block of ice. Several tons to say the least.
Since the ice began melt a few days ago. This massive block of ice has been rotating a full turn every couple of minutes.
Only thing I can think of is the wind must be hitting only part of the ice surface due to the fence and house.
 
Does it do that night and day or just during the day?? It could also be caused by the way the sun hits the pool and causes a warm spot which in turn causes the block of ice to spin
 
Coriolis effect. The Earths rotation, conservation of motion, and the fact that it is at a slant to the axis of the earths spin, cause rotation. The reason tub drains spin a whirlpool, and low pressure areas spin. In the southern Hemisphere, the spin would be reversed. Jim
 
You need to figure out how to use that free energy to generate power to supplement your house needs.
you might save a few KW each year.

It'd because of that earthquake in Chile. Didn't you read how that threw the earth a few degrees off its axis???
 
Yes. Then it's "Coriolis Force" that's giving you that effect. Now, if you could just figure out how to keep that pool frozen you'd have a real neat clock. You can adjust the velocity of rotation by moving the mass closer or farther away from the axis of rotation. I think if you'd get a lot of John Deere wheel weights and get them in near the center you could really get that thing humming. Coriolis was a french scientist who made a study of motion in a plane of rotation. His law states basically that "a rotating body will continue to rotate with the same rotational velocity until some external force is applied to change the speed of rotation". Changes in velocity will take place if the mass of the rotating body is moved closer or farther away from the axis of rotation. Think of one of your Canadian skaters starting to turn on one foot with her arms and other leg extended out from her body. Rotation is relatively slow until she moves her arms and leg in close to her body. Then, suddenly, her rotational velocity increases rapidly. Anyway, the others are right as well. It does cause objects to rotate counterclockwise in the northern hemishpere and clockwise in the southern.
 
I don't think its Coriolis effect- that only happens if the water is being drained or somehow being put in motion from other forces. Coriolis effect is only seen when you flush the toilet or drain the pool- If your pool is static, the spinning would be the equivalent of a counterclockwise current starting spontaneously in your pool or toilet while it is "at rest". More likely, it is wind drag on one part of the surface, as you postulated.

If its one of those Chinese plastic pools, and the ice is spinning as fast as you say, it should be a "transient phenomenon", and will cease when the rubbing of the iceberg wears a hole in the side of the pool and it collapses.
 
that was my 1st thought also OLD, anyway i agreewith the frenchy scientist theory,, And it could be enhanced by heat from the sun , creating warm side and cold side thermalas , i chukledabout if it were in the s.hemisphre it would melt ,, enjoyed the post !!!...
 
There is a talk show here called Garage Logic with Joe Soucherey. You hear of a lot of anomalies that have to do with our lakes here and a frequent guest when Joe needs an answer is the Lake Detective - some highly trained/edumacated biochemphysicistengineer type. The Lake Detective could probably answer your question.
Myself I think you ought to be on the lookout for crop circles as they're probably related.
 
You might just need to take off that ice blocks in your swimming pool. They are rotating because of the air breeze.
