190K views · 1.7K reactions | Let's play spies and learn chemistry in the process! Lemon juice invisible ink is a cool chemistry project that you can do at home. You just need to squeeze a lemon and write your secret message using juice as ink with a brush or a cotton bud. After your ink has dried on the paper, no one will be able to read the message unless they heat the paper. #TheDadLab #scienceexperiment #dadlife #scienceiscool #chemistry | TheDadLab | Facebook
