question: I have a closed container filled with helium and I can't change the shape or size of the container. How can I achieve maximum buoyancy in order to make the container seem as light as possible? Would I want to jam pack the container with helium so that the pressure inside container is high, or have the helium in the container be at the same pressure as the outside air, etc? This isn't a HW question, its for something I want to build. I would really appreciate any help.
