In our lives, the appearance of glow sticks has brought a lot of color to our lives. Whether it is a concert, a party, or even a walk at night, you can see the shadow of the glow stick. So, let's walk into the world of glow sticks and understand its principle and application.

The way glow sticks work is actually pretty simple. The inside of the glow stick is composed of two chemicals, one containing fluorescent pigments and phenolphthalein, and the other hydrogen peroxide. When we bend the glow stick, the two chemicals mix together and react violently, releasing energy that makes the stick glow. Moreover, by changing the type of fluorescent pigment, you can make the glow stick emit different colors of light.

Glow sticks have many different applications. In the field of entertainment, glow sticks are essential for concerts, nightclubs, parties and other activities, often adding a lot of color to the activity. In daily life, glow sticks also have many practical places. For example, we can hang glow sticks on bicycles and dog collars to alert passing vehicles. In an emergency, the glow stick can be used as a temporary lighting tool.

In general, the glow stick not only brings us a beautiful visual enjoyment, but also comes in great handy in many occasions. I hope that while using the glow stick, you can also have more curiosity and interest in the magic of chemistry, and explore more scientific mysteries.
