Why do some things float while others sink?
We have been learning about what sink's and float's
Some things float because of the buoyancy is higher than the weight that is pushing down.
Some things  sink because the weight that is pressure that is putted on it is higher than the buoyancy under.
It’s the same but the opposite.
