balloons

Balloons are flexible containers, often made of rubber or latex, that can be inflated with gases such as air or helium. When filled, they expand and take on various shapes, commonly round or elongated, and can be decorated or printed on. Helium-filled balloons float because helium is lighter than air, providing lift. They are used for celebrations, advertising, or scientific purposes, with their size, shape, and color customizable. The elasticity of the material allows them to stretch without breaking, and they deflate or burst when overstretched or punctured.
