Why don't you try the handbook layering game with fluorescent pen ink?

Scientific discovery of fluorescent pen ink 

In 1852, Stokes observed that quinine sulfate solution emitted longer-wavelength light when irradiated with short-wavelength light, such as ultraviolet. The human eye is more sensitive to certain wavelengths, and the light emitted by fluorescent dyes often falls within this range, making fluorescent colors visually striking. This is why fluorescent ink appears very eye-catching.

A helpful tool for study and work

Students can mark key and difficult points in textbooks to clarify concepts, while office workers can highlight important documents for quick reference. Using different colors for categories improves timeline clarity and boosts efficiency.
