What's the name of the flame ignition match that appeared in many movies?

The chemical substances in fluorescent sticks are mainly composed of three substances: peroxide, ester compounds and fluorescent dyes. Simply put, the principle of light-emitting stick is that peroxide reacts with ester compounds, and the energy after the reaction is transferred to fluorescent dyes, and then fluorescence is emitted. At present, a glass tube interlayer is usually placed in the common fluorescent rods on the market, and peroxides and esters are isolated inside and outside the interlayer. After kneading, the two compounds react to make the fluorescent dye glow.

At present, the luminous time of light sticks can range from 4 hours to 48 hours.

Supplementary question and answer

Fuel rods usually contain oxygen. When metals such as sodium, magnesium and potassium are used, oxygen is sent to these metals to make them react, and they can be burned in water. At the same time, these active metals reflect hydrogen in water, ignite hydrogen and release a lot of heat at the same time.

Reducing substances such as sodium and potassium were used in the underwater torch relay of Sydney Olympic Games.
