Observe the behavior of the steel ball. Does it bounce from the water surface? If not, how rapidly does it descend in the water?
Do the same with a ping-pong ball. Does it descend as rapidly as the steel ball? Why not?
And: why quotation marks for "container"?
Those words are spelled "gravity" and "buoyancy," by the way.
(Not grammar police; spelling police.)
Quotations for container because the size and shape can vary from a solo cup to an ocean. Spelling police not reqired, reading glasses police required. The coomparison still isn't valid, steel sinks, hollow thin walled plastic balls float, duh!. What does that have to do with spinning wheels?
