This Is How a Gas Balloon Climbs

Original Video Credit: IG@pilot_balonowy This person is releasing sand ballast from a gas balloon to make it climb higher. Gas balloons stay in the air because they are filled with a gas that is lighter than the surrounding atmosphere. That creates an upward buoyant force, while the weight of the basket, passengers, equipment, and ballast pulls downward. The sand is carried specifically so the pilot can control that balance. When some of it is released, the balloon becomes lighter while the lifting force remains nearly the same. That causes the balloon to rise. This gives gas-balloon pilots a simple way to control altitude without using an engine. Sand ballast is especially useful during long flights because pilots may need to climb to catch different wind currents, avoid terrain, or compensate for changes in temperature and lift. The trade-off is that ballast is limited. Once sand is dropped, it cannot be recovered, so pilots have to use it carefully throughout the flight. This video is shared for educational purposes to explain buoyancy, ballast, and how gas balloons control altitude.
