Introduction  Have you ever dreamt of being a secret agent, leaving hidden messages for your friends or decoding mysterious clues? Well, you're in luck! In this blog post, we'll explore the fascinating world of invisible ink and the science behind it. Get ready for some thrilling experiments and creative adventures! The Science of Invisible Ink Invisible ink has been used for centuries to transmit covert messages. Its charm lies in the fact that the writing remains unseen until it is exposed to a specific trigger, such as heat or certain chemicals. Let's delve into the science behind three popular invisible ink methods: lemon juice, milk, and baking soda. 1.
