Are we allowed to use helium?

Siri,
Thanks for trying. What I am trying to understand is this. You have a volume of gas at 1 atm. You have a deflated balloon, flat, no internal volume. The inside and the outside of the balloon are also at 1 atm. The volume of gas is connected to the balloon with a hose or tube. Explain how the volume of gas will somehow expand the balloon and fill it if all pressures are equal. This is what was proposed earlier in the thread. I see no force that will impel the balloon to inflate and for the gas to pass from one volume to the other.
