Why Do Ships Float -- Or Sink?The article presents science experiments to determine the factors governing the sinking or floating of ships, including buoyancy, displacement and excess weight.D'Alto, NickOdyssey
That is until it is moved or shaken about. when it may then fall below. This is the point where vinegar folks declare time of death. Since there is no more O2 or alcohol (those lighter than water attributes that keep the mushroom floating) then there is no O2 and alcohol left to ...
We’ve talked abouthealthy bathroom habitsandways to resolve constipation, and today we will discuss the buoyancy of poop in particular. Whether your poops bob at the surface or dive to the bottom can be a sign of many things to do with your health and nutritional status. Here are some o...
Why do things float in water? Objects are made up of very tiny molecules. Molecules can be packed in close together like in a rock or more spread out like in bubble wrap. The positioning of molecules affects the density of an object. Objects with tightly packed molecules are more dense th...

Today I have a fun ice boat science activity to do with kids to help teach them this concept. This would be a great activity to add to any physical science lessons. It would also make a fun summer learning activity! See also:Sink or Float: Density of Salt Water ...
As it turns out, like everything else, there is a scientific reason behind this phenomenon. But first off, let’s be clear about what makes stuff sink or float. The singular rule of thumb, when it comes to the ability of an object to float in water (or any other liquid), concerns ...
Why Nations Sink or SwimWhy Nations Sink or SwimThe U.S. is the world's largest economy while Argentina is a serial debt defaulter with a history of dictatorship. Things could have gone the other way. Both countries had ample land, natural resources, and a flood of immigrants, Alan Beatt...
The science of density and buoyancy determine whether objects will sink or float in water. If an object's density is greater than water, it will sink. Conversely, if an object's density is less than water, it will float. In the case of rubber, it floats because its density is far les...
Every once in a while, a sinksink draining slowlycauses homeowners grief. When the sink drains slowly, tasks take twice the time they usually do, or longer, because you have to wait for the water to leave your sink! This makes doing dishes and other kitchen tasks particularly frustrating as...
