Bút mực vô hình - Ẩn giấu những bí mật sâu xa nhất của bạn
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.Có gì mới trong phiên bản mới nhất 1.1.1
