There is a foolproof method to determine if there is a shark in the water. Even the experts agree that it is extremely accurate. It is based on taste. You put a little water in your mouth and swish it around so you can get a good taste. I the water tastes salty there is definitely a shark in it. If it is fresh water, no salt, does not guarantee that there is no shark in it, some do go in fresh water. But if it is salty, it's guaranteed here is a shark in it.
