WILL DATA PASS THROUGH WATER USING CONVENTIONAL METHODS?

About a year ago, my sons and I performed an experiment regarding the conductivity of salt water vs. fresh water.  It was a fun and interesting experiment for my boys, so I came up with an idea to try, playing off of that experiment. I was curious if we could get data to pass through water, using Cat5e Ethernet and replacing a length of the conductors with salt water.  In order to do this, we would need a few supplies, which include:
– Clear, non-conductive tube (at least 4 pieces)
– Clamps, to hold them in place
– Conductive salt water mixture
– Category 5e, Ethernet cable
– Computers for each side
– Ohmmeter The first step we needed to do was actually a smaller experiment, which was to determine the best salt-to-water ratio.  Our control was 1 cup of tap water.  We started by measuring the resistance with zero salt added, this yielded a result of 210 k ohms.  The next figures are the results of the same cup of water, adding 1 Tsp of table salt each time:
WATER    Tsp Salt   Resista…
