100% of hydrogen is lighter than air
Hot air, hydrogen or helium are lighter than cold air.
-- blimp -- Zeppelin -- dirigible -- hot-air balloon
When heated air is lighter than the surrounding air, it will rise due to convection currents. This process is known as thermal expansion, where hot air becomes less dense and more buoyant, causing it to ascend. This can lead to the formation of clouds and eventually precipitation.
Warm, moist, humid, air associated with a low pressure system is actually lighter than dry air - owing to the fact that hydrogen molecules in water vapor (H20) are lighter than Oxygen or Nitrogen molecules. This moist air rises - causing air pressure to be relatively low compared to surrounding air.

A REALLY big balloon filled with helium! Really, it is less denser than air, and you can make any size if you work on it. Try to make one LOL.

a castle port is an air port located near a big house.
maybe a cloud
Helium is lighter than air. hence helium balloon will float in air.
Ripley castle is big!
