This might be best determined by experiment. While natural rubber is slightly denser than water and will sink, there will be some small amount of air trapped in a rubber band ball, reducing the density to some extent. Attempting to model and calculate the air content seems somewhat impractical without experimental data, and if you are going to experiment anyway, why not just find the answer directly?
If they float in water, then it is because the density of a ping pong ball is lighter than the density of water. The density of water is just below 1, and the density of a ping pong ball is much less than 1.

Put an exact amount of water in a measuring cup. Drop in a golf ball. The increase in water level equals the volume of the golf ball, assuming the ball doesn't float. For example, 200mL before ball. 280ml after ball dropped in. Therefore volume equals 40ml or 40 Cubic Centimeters.
you want a soft rubber band ball with strechy rubber bands,but you also want to be carefull that you dont make it to big and to small
As long as it can displace a volume of water equal to its mass (ie its density is less than that of the water) it will float. Most paper will have a density less than that of water (or can be so folded) so will float.
Rubber is less dense than water, so it tends to float naturally. However, if you need to create a float made entirely of rubber, you can shape the rubber into a buoyant object like a ball or a ring to ensure it floats on water. Just ensure that the rubber is lightweight enough to stay afloat.
No, bounce balls are typically made of rubber or plastic, so they are denser than water and will sink rather than float.
Yes, a rubber band will typically float in water due to its low density and buoyant properties. The surface tension of water is usually enough to support the lightweight and flexible rubber band on the surface, causing it to float rather than sink.
No, rubber is denser than water, so a rubber stopper would sink in water.
When filled or partly filled with air, tennis balls will float. However, some of the materials in them are heavier than water. If the air is removed, some tennis balls may sink in water, as do rubber tires.
it will, unless the specific gravity of the ball is greater that the oil, if it is, it will sink. But I doubt that it is
Rubber ducks are full of air, so are buoyant on water.
Rubber is less dense than water, so it will float on the surface of the water. This is because the buoyant force acting on the rubber is greater than its own weight, allowing it to float.
No, plasticine is denser than water, so a plasticine ball will sink in water rather than float.
Rubber is not porus.
The types of objects that will float on water are foil, most rubber, and some plastic.
They are full of air, so are buoyant on water.
