Helium balloon and spinning earth question!?
Pop question that for some reason jumped into my head in bed last night and I can't quite figure out the answer to;
If I stood on the equator and filled up a Helium balloon, weighted it perfectly at 6ft so it was neither going up nor down, why would the balloon not stay in that one spot over the course of 24hrs whilst I rotated with the planet to meet it again from the other side(assuming no wind, mountains, etc getting in the way)........or would it?

The atmosphere rotates with the earth, else we would be in a 1800 kph gale (tangential velocity of the earth at the equator +/- )
So, the balloon would move with the atmosphere.
