A helium-filled balloon will sink in helium surroundings, a hydrogen surrounding or in a partial vacuum of a vacuum chamber. Here in this vid, we are able to make a helium-filled balloon sink in a partial vacuum by evacuating the air from within a vacuum chamber. We then make it rise by letting in the air into the chamber.
Ha! Thats simple....Helium has mass and due to gravity acting upon that small amount of vacuum is much larger, so due to mass and weight, it sinks...i made myself understand...
