The Little Thinkers from Azraq, Jordan feeling like super spies and wanted to send secret messages to each other! But they knew they had to be careful – how could they do it without anyone else finding out? They put on their thinking caps and came up with a plan!
First, they took some lemon juice and used q-tips to write their messages on paper. But to the naked eye, it just looked like they were drawing with a blank q-tip! That’s because lemon juice is a special kind of ink that’s invisible!
Next, they held their papers over a candle flame, being very careful not to burn them. And what happened next was like magic! The heat from the flame caused the lemon juice to darken and reveal the hidden message!
We are the Little Thinker team and we love the Science United Festival!
We love Jordan and our school, and some of us like music, others like science and experiments and others like crafts!
Let us know what you think of our experiment, we hope you like it and you can make it yourselves.
