Sorry to say, but that is an old wife's tale!

Unlike air, water is not compressible, so just going down a few feet does not result in denser
water at all (even if the pressure is a little bit higher). The only way to find denser water
would be to go down far enough to penetrate a thermocline and get into coler water - cold water
is indeed denser than warm water.

The only vessels that are going to get down that far however all have periscopes and pressure
hulls!    :-)

Cheers,
Kevin
