Why does a rubber stopper sink in water.
i cant find anything about it online.... erghh
Answer:
If the buoy is hollow, there's you're answer. The air inside will bring it's relative density to a level lighter than the water, making it float, while the solid rubber stopper has a density greater than water, and therefor sinks.
