Last year my wife and I took our kids on vacation to North Carolina. We stayed in a beach house less than a block from the water. It was there that my 2 daughters were first exposed to salt water. This year we went to the Upper Peninsula and stayed in a house on Lake Michigan. Lake Michigan is, as are all of the Great Lakes, a fresh water lake. This turned out to be a great opportunity to talk to my daughters, mainly my 6 year old, about the differences between the water and the two different beaches we've been to in the last two years.
Fresh water, of course, tastes like normal water, assuming it isn't polluted. The body needs fresh water to survive. The body can't survive long on salt water. The body can't handle the extra salt intake. The extra salt in your body causes your cells to become dehydrated and your body begins to shut down. If you've every been to the ocean, you also know that the water tastes different from regular tap water. The water tastes salty.
So there you go. If your kids ever ask why ocean water tastes different from tap water or water from fresh water lakes, now you can give them a truthful answer.
