The History of Invisible Ink
Invisible ink has been used for centuries as a way to send secret messages. The ancient Egyptians were known to use a type of invisible ink made from the juice of the tithymallus plant, which could only be seen when exposed to heat. Similarly, the ancient Greeks and Romans used a type of invisible ink made from the sap of the euphorbia plant.
In more recent times, invisible ink has been used for espionage and other covert operations. During World War II, the British government used invisible ink to send secret messages to their agents in occupied Europe. The CIA also used invisible ink in the 1960s and 1970s as part of their spy operations.
The Science of Invisible Ink
So how does invisible ink work? The basic principle is that the ink is made up of a special type of dye or pigment that is not visible to the naked eye under normal lighting conditions. However, when exposed to a specific wavelength of light, such as UV light, the dye or pigment emits light and becomes visible.
Invisible ink can be made using a variety of materials, including lemon juice, baking soda, and food coloring. The recipe we'll give you below uses a combination of lemon juice and baking soda to create a simple invisible ink.
How to Make Invisible Ink
Making invisible ink is easy and fun, and can be done with just a few simple ingredients. Here's our recipe:
Ingredients:
1/2 cup lemon juice
1 tablespoon baking soda
1/4 cup water
A few drops of food coloring (optional)
Instructions:
In a small bowl, mix together the lemon juice and baking soda until the baking soda is fully dissolved.
Add the water to the bowl and stir until the mixture is well combined.

Use a cotton swab or a small brush to apply the invisible ink to the paper or surface you want to write on.

To reveal the message, simply hold the paper or surface up to a light source or use a UV light. The message will appear in a faint color.
