How can you make a hot air balloon fly?

Answer 1

Hot air balloons are made of lightweight manmade fabric cut from a pattern and sewn together on a sewing machine. A basket is suspended below it with a burner that heats the air on the inside. the basket is woven from rattan cane so that it will be as light as possible. Propane fuel is kept in containers in the basket to fuel the burner. It's pretty simple but a lot of work.

Answer 2

put hot air in it ;p hahhahaha

Hot air is lighter than the surrounding air as it is less dense (molecules move apart.) Therefore, it always wants to rise (as it does in your home, making higher floors hotter than lower floors.) When you trap hot air in an air-tight space as with a hot air balloon, it wants to rise, taking the balloon with it.

So a hot air balloon does not need to be made to fly. It needs to be tethered to the ground to keep it from flying.
