Invisible ink was invented by Benjamin Franklin and is currently used in government documents as a secret code. Benjamin Franklin used lemon juice as the first invisible ink. The acid in the lemon juice weakens the paper where it has been spread. Therefore, if the paper is held over a candle or another heat source, the area where the lemon juice was spread will burn more easily. This will reveal the placement of the lemon juice.
