    Swim under water and listen to the noises.

    In order to do this, the source of the sound has to NOT be touching the sides of the pool. For example, if you STAND in the pool and shout to your friend, you cannot tell that the sound hasn't gone through your feet, across the cement bottom of the pool, and up your friends legs to his or her ear.

    I recommend taking a saucepan and a metal stick into the pool. Have your friend stand in the shallow end and keep at least ONE ear in the water.

    Note that it doesn't matter if your friend is touching the bottom - you only need to proove that the sound traveled through the water for some distance. If it traveled to the bottom, through the cement, up her legs to her ear, that's OK because it had to travel through the water to get to her.

    Of course you could reverse the rules; you stand in the shallow end with the pan and stick, your friend dives in the deep end, and while she is underwater you hit the pan (or not). When she comes up you ask her if you hit the pan or not.

    Then, you get into the deep end, in water too deep to stand, and you're going to have to put your entire body underwater so that nothing breaks the surface. Smack the pan some number of times with the metal stick and ask your friend to tell you how many times you hit the pan.

    What is important is to have NO part of you or the pan or stick touch the bottom, sides, or surface of the pool. Otherwise you have not proven anything; the sound could have found a different route.

    Try this:

    Take a friend to a swimming pool. You stand at one end, underwater; your friend at the other end, underwater.

    Have a secret list of words and/or numbers that your friend doesn't know. For each word on the list, shout underwater to your friend underwater. Have the friend write down what he/she hears. Repeat experiment with a new list. Keep track of the words and what your friend heard (data).

    If all goes well, you can show a high percentage of words that were successfully transmitted. You can then come to the conclusion that sound travels through water.

    Hope this helps!

    Stick your head underwater, say a pool. Take a stick or hammer and, while floating (not touching the sides), have a friend hit the side of the pool. Hearing the sound proves sound traveled through the water to your ears.

    Most of these answers would work fine. The problem is, any sounds you hear underwater (with your own ears) will seem to come from all directions at once. This is because sound waves travelling underwater will reach both ears at almost the same time, so your brain cannot distinguish which direction they came from.

    Source(s): I think I learned that from playing Mindtrap II.

    Put your head underwater and scream. Now can you hear yourself ? If not try the experiment again you didn't do it right. If you did hear yourself don't you feel dumb for doing this in the first place. just kidding.
