gas balloons
Gas balloons are inflatable devices filled with a lighter-than-air gas, such as helium or hydrogen. This makes them buoyant, allowing them to rise in the atmosphere. The principle behind their lift is based on Archimedes' principle, where the lighter gas inside the balloon displaces a greater weight of air. Gas balloons are commonly used for celebrations, weather monitoring, and scientific research. While helium is safer and non-flammable, hydrogen is cheaper but poses a risk of explosion. Overall, gas balloons are fascinating tools that demonstrate basic principles of physics and buoyancy.
