For those guys old enough to remember tying a string between 2 cans and running it across the room,,,,,if one of the two cans were under water,and the can were surrounded by a object to prevent water from filling in the can.....would the sound still transmit to the inside of the can?

Do your own homework.

If the string is also in water it wont vibrate, so no, no sound would be transmitted (or at least not at a frequency you could hear).

Is the string  waxed ?

Only if the can is on a treadmill.

The can underwater, or the can above water?
This is important

A guy from work is telling me they used to use a similar device back in the 70's during underwater welding operations..i said bs..it would not be able to vibrate the string..he claims they had some kind of amplifier.

very much under wqater would tend to dampen the string vibrations id guess you would not get much distance at all like this.

At least I'm not the only one

Submarines use sound powered telephones....

So yes... the sound will transmit through the wire as long as the water is not touching the wire. I used a sound powered phone under water and it worked fine

I know... not the answer you were looking for.....

does your gym have a pool or hot tub?

you should prove him wrong.

If the string is not protected from the water you would need some type of amp to be able to hear it I would think.

Edit; beaten to it

This needs real world testing.

First, you and your co-worker consume enough beer that each of you thinks the other is inebriated.

Second, both of you open a can of Campbell's chicken noodle soup (this will remind you of being a kid and make it more fun.  Studies have shown that research done with Campbell's soup is much more fun than research done with Progresso or other soups).  Then eat the soup, basically drink it straight from the can.  You're grown men after all so you shouldn't be afraid of some cold soup.

Third, string.  You'll need string.  How you get the string is up to you, but I would suggest listening to the beer for ideas.

Fourth, put it all together along with the contraption to keep water out of the other can, making sure that you can still get the under water can to your ear.

Fifth, and this is where is gets tricky.  One of you has to get down to his speedo's and get in the water.  This time of year this is going to be a penis shrinking ordeal so if that's your thing you get in the water, if not, have him do it.  Either way you're flirting with gayness by this point ("Not that there's anything wrong with that." Jerry Seinfeld).

Sixth, if neither of you has drowned at this point, post pictures and results.

The string would have to be encased in a tube.  I don't believe it would vibrate enough if submerged in water.

I don't think the string vibrates. It seems to me that it oscillates in a linear direction parallel to it's length. So I see no reason why water would stop the string from carrying the message. Maybe the water will dampen the diaphragm though.
