Balloons are given for special occasions, such as birthdays or holidays, and are often used as party décor. Legislation regulating the release of balloons". Clean Virginia Waterways.

Balloon artists are entertainers who twist and tie inflated tubular balloons into sculptures such as animals (see balloon modelling). The balloons used for sculpture are made of extra-stretchy rubber so that they can be twisted and tied without bursting. Since the pressure required to inflate a balloon is inversely proportional to the diameter of the balloon, these tiny tubular balloons are extremely hard to inflate initially. A pump is usually used to inflate these balloons.

Balloons are certainly better than satellites at rattling the targeted country, and caused a minor political storm in the US, with Republicans calling for the balloon to be immediately shot down over land, despite the risk of deaths and property damage below.

The theory, then, suggests that the balloons are a representation of the deadlights and contain the souls of the children killed by IT. The deadlights could be described as a sea of bright, orange balloons, which Pennywise takes a bit too literal. The strings of the balloons resemble the spider legs of IT’s final form, and when taking the films’ representation of the deadlights, they could also be a nod to the strings connected to the deadlights. What makes the balloons float is not helium, but the souls of all the children Pennywise has killed, hence why his famous “ they all float down here” quote.

For example, the balloon of a Foley catheter is inflated when the catheter is inserted into the urinary bladder and secures its position. [12] Once inflated with regular, atmospheric air, the air inside the balloon will have a greater air pressure than the original atmospheric air pressure. [31] Decorators may use helium balloons to create balloon sculptures. Usually the round shape of the balloon restricts these to simple arches or walls, but on occasion more ambitious "sculptures" have been attempted. It is also common to use balloons as table decorations for celebratory events. Balloons can sometimes be modeled to form shapes of animals. Table decorations normally appear with three or five balloons on each bouquet. Ribbon is curled and added with a weight to keep the balloons from floating away. The protests left many furious that the popular fun family event had been dragged into politics - while others commented on how the broadcast coverage appeared to purposefully avoid showing the disruption taking place.

Further deflations hit the Diary of a Wimpy Kid and Monkey D. Luffy, after both characters got snagged on overhanging trees and obstacles that popped the huge balloons. The New England Native American float sparked outrage earlier in the morning as one performer held a Palestinian flag aloft while the annual extravaganza moved through Midtown Manhattan. Filling the balloon with air can be done with the mouth, a manual or electric inflater (such as a hand pump), or with a source of compressed gas. For decades, people have also celebrated with balloon releases. 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 potentially injurious to animals, the environment, and power lines. Many states now have banned balloon releases.Loud boos rang out from the crowd as the white jumpsuit-clad protestors poured fake blood over themselves and held up the parade for thousands, as they appeared to try and link the crisis in the Middle East to climate change, shouting: 'Liberation for Palestine and climate.'
