Because the balloons are so large even a light breeze will blow them sideways.
You cant because his in the air
Heating the gas in the balloon makes it less dense, causing it to become lighter than the surrounding air. This creates a buoyant force that lifts the balloon upwards. As the gas cools, the balloon descends back to the ground.
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
The fire warms up the air and the air becomes less dense. So the balloon traps the warm air and since less dense gases rise with denser gasses around it, the warm air rises taking the balloon with it.
To demonstrate that air occupies space, you can use a simple experiment by inflating a balloon and then placing it in a container filled with water. As the balloon is submerged into the water, you will notice that it displaces water, showing that the air inside the balloon is taking up space.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
to fly that far in a hot air balloon it would take up to at least over 15-30 days but that also depends on how fast you get the hot air balloon to fly and if you stay straight on course

When a balloon is inflated, it stretches and expands in size, showing that the air being blown into it is taking up space inside the balloon. As more air is blown in, the balloon gets bigger, demonstrating that the air molecules are displacing the surrounding air and occupying a definite volume within the balloon.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
The perimeter of a hot air balloon is the sum of the lengths of all its sides. Typically, hot air balloons do not have a traditional perimeter measurement as they are not geometric shapes with straight sides like squares or circles.
