i think it takes a long time for a hot air balloon to fly

Yes, helium will help a balloon fly. Helium does not affect the direction that a balloon goes, but it will keep it in the air for quite some time.
The force of buoyancy, which is created by the displacement of air by the balloon, allows it to fly. This force is greater than the weight of the balloon, causing it to rise.
Yes they were first to fly the first hot air balloon
Put a straw in the end of it and blow into the balloon. That should make it fly straight although make sure you don't use helium and make sure there is as little of wind around as possible. From Matthew
