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.
Yes and no. Rubber bands can float and sink in water. They will float on the water for awhile and then will sink. But not all the time the rubber bands will float on the water for awhile. Sometimes it will immediately sink.
i don't know... That's why I'm asking you. soo.. Does a rubber stopper float 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.
Rubber ducks are full of air, so are buoyant on water.
float
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 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.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
Yes.
