Any gas with a density higher than air. Carbon dioxide will do it, krypton is denser still, and will make it drop quicker. There are others too.

What gas does make a balloon float?

Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.


What makes a balloon float on water?

A balloon filled with a gas that is less dense than water, such as helium or hydrogen, will float on water due to the buoyant force acting on it. The gas inside the balloon displaces an amount of water equal in weight to the balloon, causing it to float.


Is there something else to float a balloon?

Why do baloons float in air?

Balloons float in air because they are filled with a gas that is lighter than the surrounding air, usually helium or hydrogen. This creates a buoyant force that pushes the balloon upward, causing it to float.


What makes a helium balloon?

A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.


Will ammonia gas float a balloon?

No, the density is too high.


What gas do you use to make a balloon float?

Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.


What must happen for a balloon to float in the air?

For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.


What happens when you stick a balloon to glass will it float?

When you stick a balloon to glass, it will not float on its own. The balloon will stick to the glass due to static electricity generated when rubbing the balloon against your hair or clothes. The balloon's ability to float is determined by the gas inside the balloon and the upward force it creates, not by sticking it to a surface.


What can you say about the gas inside a balloon?

The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
