Why things float and sink ?

Some things float because they are light or the walls are high enough . Like on the foil boats you have to make the bottom flat.On the soap boats you have to make the walls high enough.

Some things sink because the have holes ,or the walls are not high enough. Some things do not float be cause there heavy or you dident carve it enogh.



Some things float becaus ther light and others are hevey.

An object floats when weighs less than the weigh of the fluid it displace.
But in some fluids some of the things will float and in other fluids they will not.
