Sink (May 3)
If you put something in water, one of two things will happen. The option that most humans are glad to discover is that an object can float. The other option that puts fear into humans is that something can sink. Now we know that density determines if an object will float or sink in relationship to the density of water, at least the particular water at hand should it have minerals in it thus increasing its density from the regular density of pure water. Still, even though a density may be less than that of water, currents in the water could cause something to sink as well. The bottom line is that it comes down to knowledge. If you have a rock that you do not want to loose, you do not throw it into the deep point of one of the great lakes. If you have a piece of wood that you don't want to loose make sure you don't put it in water with a current that will pull it under. It seems to me that the tendancy of humans in general is to test the water. This philosophy is like throwing rocks into water expecting them to float. Surely there is enough information out there that one should be able to weigh the facts and then make a decision not to watch the rock sink in the water. Still there are other people out there that make arguements on political or moral instances in particular that have the same effect as throwing rocks into water expecting them not to sink. If you do not want to sink make sure you check the density and currents first.
