When you immerse an object in water you are claiming a space that would otherwise be filled by water. So where does that water go? Up! Just like a baseball wants to drop down if you let it go, that displaced water is competing to reclaim its space by going down. In the process it is pushing the object upward. If the weight of that object is smaller than the liquid it displaced, it will be balanced by only pushing it partly above the surface of water. This is the so called “floating”
