WebMolecules are very, very tiny. You can only see them with a special microscope. In some objects, like a rock, molecules are squished tightly together. In others, like wood, the molecules are more spread out. How closely molecules are crowded together in a space is called density. ... The materials that can float in water is: 1. Cube. 2. Pencil ... WebWhen an object sits in water, the water pushes underneath it, creating an upward force called buoyancy. If the weight of the object is bigger than the buoyancy, the object will sink to the bottom. If the buoyancy is bigger than the weight, the object will float.
