A balloon launcher is a device designed to propel balloons into the air. It typically consists of a mechanism that uses air pressure or a spring to create force, allowing the balloon to ascend quickly. These launchers can be used for various purposes, including scientific experiments, celebrations, or simply for fun. Balloon launchers can vary in size and complexity, from simple handheld models to larger, more sophisticated systems. They are often used in educational settings to demonstrate principles of physics, such as force and motion, and can also be part of events like birthday parties or festivals.
