The balloons that float usually contain helium in them, which is lighter than air. This enables the balloon to float.

Hot air balloons float because hot air displaces cool air in the atmosphere
They can make u float if u get enough dumb bum
Try looking up fun facts of hot air balloons. Learn all you can about them, history and common uses. Then you will sure find some great things to write about.
a hot air balloons floats. something to do with buoyancy
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Helium
Magic...
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
At a hot air balloon festival, hot air balloons slowly fill and then rise majestically in the predawn sky. These hot air balloons fly because of two fundamental principles of physics: the ideal gas law and Archimedes's principle.
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Helium is lighter than air, hence balloons filled with helium will float and rise up.
they float and pop
Because air is not as dense as helium filed gallons so they won't float
Helium is lighter than air.
