1. Blow the blower against the balloon on the ground, and the balloon will float;

2, charging hydrogen and helium;

The balloon floats because of air convection or the gas density in the balloon is less than air, which leads to the balloon's small mass and can float.

Balloons usually blown by mouth are easy to sink, because the main gas component is carbon dioxide, which is denser than air, while balloons blown by pump will not float, because the gas component is the same as air and the quality is the same.

Therefore, the balloon can be floated by making the air flow; Or balloons filled with hydrogen or helium with a density lower than air can float.
