Yes it will, if it's inside the balloon and hot enough.
It actually won't. CO2 is a heavier gas than Earth's atmosphere, so it will sink. Think about it- we breathe out carbon dioxide, and balloons we blow up the normal way don't float.
Fill a balloon part way with helium, make an animal out of it and have it float.
Heilum combined with the light material of the balloon make it as light as air making it float.
Helium goes into a balloon to make it float.
helium gas
Yes.
That would be Helium
a balloon float on water
Yes.... See Hindenburg.
gas yes boy
Instead of blowing normal air (your breath, a pump, etc.) into the balloon, you'd use helium to make it float.
yes, but it will actually make you float up in the air
Helium gas is lighter than air and hence balloons filled with helium will float in air.
