Why was the glow stick invented?

The glow stick was invented as a portable and safe source of light for various applications, including military use, emergency situations, and recreational activities. Its design allows for a chemical reaction to produce light without the need for electricity or flames, making it ideal for low-light conditions. Initially developed in the 1960s, glow sticks have since become popular for events, parties, and safety signaling. The invention aimed to provide a convenient and versatile illumination option.
