Some balloons just have air (the inflated ones used as decorations). The ones that rise in the air are filled with helium, a gas much less dense than air. The large balloons that carry people aloft are lifted by hot air, using propane burners. Hot air is also less dense than cooler air. The weather balloons that rise to great heights are filled with helium or other gases, and some inevitably pop when they expand to their limit in the upper atmosphere.

What air is inside balloons?
helium
What is the sticky stuff on the inside of balloons?
The sticky stuff inside balloons is called balloon lubricant or powder. It helps prevent the sides of the balloon from sticking together or to itself when inflated, making it easier to inflate the balloon.
What happens to balloons when the sun makes them hotter?
When balloons are exposed to the sun and become hotter, the air inside them expands. This causes the balloons to increase in size and potentially burst if the pressure inside them becomes too high. It's important to monitor balloons when they are in direct sunlight to prevent them from overinflating.
The shape and the size of a toy balloons depend on the kind of gas inside?
Yes, the shape and size of a toy balloon depend on the type of gas inside. Helium makes balloons float, while air or carbon dioxide results in balloons sinking. The gas affects the overall buoyancy and volume of the balloon.
How was Hydrogen kept inside the Hindenburg?
In several big balloons or bladders inside the outer casing.
Why must all you birthday balloons pop?
The air inside the balloons eventually escapes out of it so the balloon becomes empty of air.
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Are you supposed to play with hamleys magic balloons inside or outside?
Anyhow
Why do balloons shivrelled up on a cold night?
Balloons shrink on a cold night because the air inside them contracts as it cools down. This reduces the volume of air inside the balloon, causing it to shrivel up.
How many 9 inch diameter balloons could 11 gallons of 125 PSI air fill?
The answer depends on the pressure inside the balloons.
How do balloons float?
Balloons that are filled with hot air, hydrogen, or helium will float, or rise upward, because the less-dense gases inside them are displaced by the heavier air around them. Balloons will only rise until the gas density inside them is equal to the density outside. In the case of helium balloons, this may be above the elastic limit of the balloon, and it will pop or leak.
Can same type of balloons withstand the same amount of pressure?
Yes, no matter how much air is filled inside of the balloons.
