No, lower temperatures and pressure cause balloons to collapse.
yes
The balloons that float usually contain helium in them, which is lighter than air. This enables the balloon to float.
So the blimp will stay aloft/still adn will float.
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
they float and pop

The game is called Float.
Hot air balloons float because hot air displaces cool air in the atmosphere
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
You may use airplanes or balloons (aeronautics).
