It Doesn't. Actually the foam balls themselves has weight and therefore presses down on the vessel.
Yes, a capped, empty, plastic water bottle will almost always float in water. This is because the density of plastic water bottles (the 12- or 20-oz kind) is very low compared to water itself. As long as it is empty and capped, no water will enter the bottle while it is tipped over in the liquid, and so it will not be weighed down by the addition of any liquid.
Any substance that has a density less than of water will float in it. For eg. wooden logs, ice, paper, ships, empty plastic bottles, etc.
No, they are not bouyant. They won't float on water, but they will float on mercury.
Because it is much denser than water. If u had liquid with higher density it would float

Well balls float-cos the force of upthrust from the water is pushing them up-and is stronger than gravity.The surface area increases the upthrust-which is why pumped balls float better than deflated.
Whether an object sinks or floats depends on the objects buyoncy. If an object has a higher buoyancy then water it will generally sink, and less it will float.
It'll float
If it is empty and you seal it, it will float. Possibly would float if it were flattened.
A plastic always sink in oil like a plastic bottle will always float in oil.
All plastic items float on water, so therefore a plastic boat floats on water.
plastic will float in water because it is lighter than oil
