Please note: This is a general guide that illustrates the approximate number of balloons you can fill based on helium cylinder sizes under optimum conditions. The actual number of balloons filled may be slightly more or slightly less depending on usage.

This practice has been discouraged by the balloon industry, as it has posed problematic for the environment and cities. In recent years, legislation, such as the California Balloon Law , has been enacted to enforce consumers and retailers to tether helium-filled foil BoPET balloons with a balloon weight.
This ensures that the helium-filled balloons do not float into the atmosphere, which is both potentially injurious to animals, the environment, and power lines. Many states now have banned balloon releases. It is becoming more common for balloons to be filled with air instead of helium, as air-filled balloons will not release into the atmosphere or deplete the earthly helium supply. There are numerous party games and school-related activities that can use air-filled balloons as opposed to helium balloons.
When age-appropriate, these activities often include the added fun of blowing the balloons up.
In many events, the balloons will contain prizes, and party-goers can pop the balloons to retrieve the items inside. Balloons are used for publicity at major events. Screen printing processes can be used to print designs and company logos onto the balloons. Custom built printers inflate the balloon and apply ink with elastic qualities through a silk screen template. Also in the s at the start of the Cold War, activists in Western Europe uses balloons for propaganda purposes that would float east over Eastern Europe, which would release newspapers and pamphlets. Today, South Korean activists are using the same balloon method to get information to those in North Korea.
Paolo Scannavino set the record of 11 for the most giant balloons entered in 2 minutes. Water balloons are thin, small rubber balloons filled with a liquid, usually water, instead of a gas, and 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, competition, or practical joke.
By forcing water out the open end of a water balloon, it is possible to use it as a makeshift water gun. Solar balloons are thin, large balloons filled with air that is heated by the sun in order to decrease its density to obtain lift. Balloons are often deliberately released, creating a so-called balloon rocket. 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. Balloons filled with hot air or a buoyant gas 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 as the lifting gas. Later, coal gas and later still helium were used. An unpowered balloon travels with the wind.
Helium cylinders & balloon capacity: A quick & easy guide
A balloon which has an engine to propel it is called a dirigible balloon or airship. Angioplasty is a surgical procedure in which very small balloons are inserted into blocked or partially blocked blood vessels near the heart. Once in place, the balloon is inflated to clear or compress arterial plaque , and to stretch the walls of the vessel, thus preventing myocardial infarction. A small stent can be inserted at the angioplasty site to keep the vessel open after the balloon's removal. Balloon catheters are catheters that have balloons at their tip to keep them from slipping out.
For example, the balloon of a Foley catheter is inflated when the catheter is inserted into the urinary bladder and secures its position. Insertion of balloons subsequently filled with air or liquid can be used to stop bleeding in hollow internal organs such as stomach or uterus. There has been some environmental concern over metallised nylon balloons, as they do not biodegrade or shred as rubber balloons do. Release of these types of balloons into the atmosphere is considered harmful to the environment.
This type of balloon can also conduct electricity on its surface and released foil balloons can become entangled in power lines and cause power outages. Released balloons can land anywhere, including on nature reserves or other areas where they can pose a hazard to animals through ingestion or entanglement. Because of the potential harm to wildlife and the effect of litter on the environment, some jurisdictions even legislate to control mass balloon releases. Legislation proposed in Maryland , US, was named after Inky, a pygmy sperm whale who needed six operations after swallowing debris, the largest piece of which was a Mylar balloon.
However, a latex balloon can take up to a year to degrade if it lands in the sea and during this time it is possible for a marine animal to ingest the balloon and die from slow starvation if its digestive system is blocked.

When balloons eventually return to the ground, they begin the degradation process. Latex balloons are the most used because of their ability to biodegrade. The problem with this is that it can take at least 4 weeks to show substantial degradation of the polymer in the environment, and around 6 months in aquatic environments. When that happens, it can lead to negative effects for the animals. For example, a bird will use a deflated balloon as a component for its nest.
When the eggs hatch, they will get tangled in the balloon and that can lead to death. Once inflated with regular, atmospheric air, the air inside the balloon will have a greater air pressure than the original atmospheric air pressure. Air pressure, technically, is a measurement of the amount of collisions against a surface at any time. In the case of balloon, it's supposed to measure how many particles at any in any given time space collide with the wall of the balloon and bounce off.
However, since this is near impossible to measure, air pressure seems to be easier described as density. The similarity comes from the idea that when there are more molecules in the same space, more of them will be heading towards a collision course with the wall. The first concept of air pressure within a balloon that is necessary to know is that air pressures "try" to even out.
As air pressure itself is a description of the total forces against an object, each of these forces, on the outside of the balloon, causes the balloon to contract a tiny bit, while the inside forces cause the balloon to expand. With this knowledge, one would immediately assume that a balloon with high air pressure inside would expand based on the high amount of internal forces, and vice versa. This would make the inside and outside air pressures equal.
