because the sound reverberates in your skull, and with the water acting as a sound proofing, there is very little distraction noise-wise and the whispering becomes clear.  Basically you are hearing from the inside out.  Now when you come out of the water, there is water in your ears, and you no longer have the insulation of the water around your head.  That, combined with the noise of sitting up, the water splashing around you, the ambient noise from your surroundings, causes you to not recieve the soundwaves, which are now outside of your head and "mixing" with the rest of the noise.\n\nGet it?

It lodges around your ear drum...like the first person said...it usually stays in your canal...until it ether evaporates or you pump it out

rather odd coming from a guy, but what to hell, while you are taking a shower just relax and let it happen, then practice practice. There I said it

the water that gets trapped in your ear is really bad.. normally your ear works its magic and the water drips out, but if you cant get it out use an alcohol solution that will rinse the ear and then evaporate\n\nNEVER use a Qtip.. cause you can seriously hurt your inner ear

I burst my eardrum and even when i was told that it was healed, everytime i swam my ear started aching, rather not swim to prevent further damages! If you must then get ear plugs or something that will prevent water splashing into your ear, don't go underwater.

You're suppose to breathe in through your mouth and breathe out through your nose in the water.

Hey I was thinking that it sounded more like a penis. Is it a penis? I've never squirmed while brushing my teeth. My toothbrush doesn't really hang loosely either.

Please.  Your lungs can not be down as much as 3 feet I believe, or the air would be forced out of your lungs.  Now if you snorkel at normal depth, you can hold your breath and go down as far as you can make it.  But you can't breath continuously unless the air is being pumped.  Your head will not collapse, it's filled with liquid which doesn't compress.

you could breathe through a tube down as deep as perhaps one atmosphere.  beyond that the surrounding water pressure on your chest would prohibit you from taking a breath from surface air.

the acoustics in bathrooms sound cool! Maybe were so happy to be clean we want to sing in happiness. This is where most people get they idea that they can sing as there's some law of physics happening right there that makes many of us  mortals sound like great singers! OoOOoooOOoO yaeaahh!

It's a form of underwater swimming

This is usually because you're also swallowing a large amount of air that has become trapped under the descending liquid. You may notice that you belch shortly after this happens.

Having been in the stuff while my more experienced friends stood around and laughed, I can tell you -\n\nYou won't drown.  Its just like water, only thicker.  It doesn't "suck you down".  Stay calm and swim out slow motion.

You and your friend should take turns watching each other pee as that is how I learned. My girlfriend simply positioned herself over me while I was lying in the tub. In order to get a clear view you will have to hold open her lips and a pair of goggles or glasses would help the viewer.
