Invisible inks are made from a number of common household items. Lemon juice is one of the best sources of invisible ink. Its citric acid is absorbed into the paper as carbohydrates.
Another common secret message ink is apple juice. This can be heat-activated to reveal the message. You can also make your own invisible ink using lemon juice or milk.

Invisible inks are based on an acid-base reaction. This is a natural process that is often used to develop messages on paper. However, other chemicals can also be used to develop the message.
