Balloon Publicity

Balloons are often used for publicity at major events. Screen printing processes can be used to print designs and company logos onto the balloons.

Water balloons

Water balloons are thin, small rubber balloons intended to be easily broken. They are usually used by children, who throw them at each other, trying to get each other wet, as a game or practical joke. They can be used in competitions or games. They are often smaller than regular balloons.

Balloon rockets

Main article: Balloon rocket

Balloons are often deliberately released, creating so called balloon rocket or rocket balloon. Rocket balloons work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is left open, the gas within the balloon shoots out, and, due to Newton's third law of motion, the balloon is propelled forward. This is fundamentally the same way that a rocket works.

Flying machines

Main article: Balloon (aircraft)

Large balloons filled with hot air or buoyant gas (often hydrogen or helium) have been used as flying machines since the 18th century. The earliest flights were made with hot air balloons using air heated with a flame, or hydrogen; later, helium was used. Unlike airships, balloons’ travel is directed exclusively by wind.
