    Do you think plastic straws are banned in the places with waste management that allow plastics to be dumped in the ocean?

    Ed. There is an effect of buoyancy that will make denser things fall faster. It becomes noticeable in distances where the dropped items reach terminal velocity or on more dense media where buoyancy is more significant.

    In air over short distances buoyancy is negligible, in vacuum there is none
