قلم حبر غير مرئي - حافظ على أعمق أسرارك مخفية
Invisible ink pen contains a special type of ink made from naturally fluorescent chemicals or organic compounds. When you shine a UV light down on a message or drawing made with invisible ink, the electrons within the ink’s fluorescent molecules are excited, briefly shifting to a higher-energy orbit around their nuclei. When those electrons shift back to their normal orbit, the absorbed energy is expelled in the form of visible light.تحديث لأحدث إصدار 1.1.1
