Why Does It Work?

Lemon juice is an organic substance that oxidizes and turns brown when heated. Diluting the lemon juice in water makes it very hard to notice when you apply it the paper. Other substances which work in the same way include orange juice, honey, milk, onion juice & vinegar. Invisible ink can also be made using chemical reactions or by viewing certain liquids under ultraviolet (UV) light.
