Balloon skewer experiment. A pin or needle is frequently used to pop a balloon. [4] As the needle or pin creates a hole on the balloon surface, the balloon pops. However, if tape is placed on the part where the hole is created, the balloon will not pop since the tape helps reinforce the elastic tension in that area, preventing the edges of the hole pulling away from the center.

However, they were not as durable as regular balloons, and could pop easily if overinflated, handled with too much force, or squeezed. Chemically, the bubbles contained polyvinyl acetate dissolved in acetone, with ethyl acetate plastic fortifiers added. The acetone evaporated upon bubble inflation leaving behind a solidified plastic film. [1]
Fig. 2. Pressure curve for an ideal rubber balloon. When air is first added to the balloon, the pressure rises rapidly to a peak. Adding more air causes the pressure to drop. The two points show typical initial conditions for the experiment. When the valve is opened, the balloons move in the direction indicated by the arrows.

Party balloons are mostly made of a natural latex tapped from rubber trees, and can be filled with air, helium, water, or any other suitable liquid or gas. The rubber's elasticity makes the volume adjustable. Twisting balloons can be used to create decor centerpieces for events and to create a more unique look than can be provided by foil balloons.
Inflated party balloons. A toy balloon or party balloon is a small balloon mostly used for decoration, [1] advertising and as a toy. Toy balloons are usually made of rubber or aluminized plastic and inflated with air or helium. They come in a great variety of sizes and shapes but are most commonly 10 to 30 centimetres (3.9 to 11.8 in) in diameter.
Balloons are not inherently bad, but when humans let them float away, those party favors can turn into hazards for marine life. Editorial: Balloon bans are the result of humans acting ...
