hot air rises
balloon stay up because of the air inside it. to make the balloon stay up the air should be light. inside the balloons you can find the air we called helium. helium is a light air that makes the balloon stay up. that's why if you blow the balloon it wont float because the air that comes from your mouth is not helium but carbon dioxide and carbon dioxide is heavier compared to helium so it wont float.
There are a variety of balloons available, including latex balloons, foil (mylar) balloons, helium balloons, air-filled balloons, water balloons, and LED light-up balloons. Each type serves different purposes, from decorations to entertainment.
Balloons, airplanes, and rockets are things that go up.
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.

Helium
To make balloons stick together effectively, you can use a special adhesive designed for balloons or a hot glue gun. Apply the adhesive to the areas where you want the balloons to stick together, then press them firmly together and hold them in place until the adhesive sets. This will help the balloons stay connected securely.
to make your voice squeak and blow up balloons
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
the balloons that make noise is called screamers
Weather balloons typically stay aloft in the atmosphere for about 12 to 24 hours before they burst and fall back to the ground.
Air can escape from the ballons even if there aren't holes in them.
