There are several reasons why your lemon juice invisible ink may not be working as expected. One common reason is that the lemon juice may be too diluted, making it difficult to see the writing. Another reason could be that the paper you are using is not reacting well with the lemon juice, causing the writing to be faint or not visible. Additionally, the heat source you are using to reveal the writing may not be hot enough to activate the lemon juice. Experimenting with different concentrations of lemon juice, types of paper, and heat sources may help improve the visibility of your invisible ink.
