The lower pressure balloon will expand. Figure 2 (above left) shows a typical initial configuration: The smaller balloon has the higher pressure because of the sum of pressure of elastic force Fe which is proportional to pressure (P=Fe/S) plus air pressure in small balloon is greater than air pressure in big balloon.
A balloon is an inflatable flexible filled with air and also gas, such as helium, hydrogen, nitrous oxide or oxygen. Modern balloons can be made from materials such as latex rubber , polychloroprene , or a nylon fabric, while some early balloons were made of dried animal bladders [ citation needed ] .
Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.
A dozen or so hot air balloons, some 1,600 feet above ground level, scattered a sky that soon would fill with hundreds of more balloons for the 52nd Albuquerque International Balloon Fiesta.
Typically, a helium-filled latex balloon that is released outdoors will stay aloft long enough to be almost fully deflated before it descends to Earth. [7] However, the Balloonfest balloons collided with a front of cool air and rain, which caused them to drop towards the ground while still inflated.
The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight in the world was performed in Paris, France, by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, [1] in a balloon created by the Montgolfier brothers.

Geostationary balloon satellites (GBS) are proposed high-altitude balloons that would float in the mid-stratosphere (60,000 to 70,000 feet (18 to 21 km) above sea level) at a fixed point over the Earth's surface and thereby act as an atmospheric satellite. At those altitudes, air density is around 1/15 to 1/20 [37] of what it is at sea level ...
