I tested in a pool how magnets behave underwater, but it seems they move fall quicker underwater than in air, so i tried again, same result, i tried in a bathtub with and without water... again, same result... I'd like to know why this happens...

edit: ok, it was visual, but it was still quite a significant change of speed, i dropped it from the surface of the water and it took less time to fall from the surface to the bottom with water than without...

ok look, i was underwater with the magnets, i'm not sure if there was a magnetic field underneath or the magnets were made much more sensitive or something, but it is kind of odd that this happened many more times than once...

This would be almost impossible unless the magnet's pull was affecting the data. Were you testing with a metal container? If so then use glass. The resistance offered by water is much higher than the air so it should fall slower. The pull of gravity will also work faster in air than in water. (again teh resistance is less)

I'd check your results. Water should offer greater resistance to falling than air, so everything should fall more slowly in water.
How did you measure the difference? Was this perception, or did you somehow time the magnet's fall over a known distance?

I'd like to know how you are able to measure how long it takes a magnet to fall only a foot...or even the few-foot depth of your average pool. You're talking times in a small fraction of a second.
Frankly, I think your perceptions are flawed.

Since water refracts light much more than air, it is possible that the water is distorting the image of the magnet and making it appear to be moving faster than it really is.

Is the bathtub you are using cast iron by any chance? (Covered with enamel). Perhaps the magnets are pulling toward the iron, otherwise, your perception if flawed.

Not true. Go back to the drawing board pal.

Get a big pyrex bowl and try your test again.

May be magnets know diving.
