Many science experiments are amazing. This time, let's make magic ink and expose the secrets behind the amazing possibilities of science.
First, prepare the materials, such as lemon, water, a small plate, a toothpick, white paper and lamp.
Now, let's start. First, squence the lemon into a small plate. Mix it with a few drops of water using a spoon. Then, dip the toothpick into the lemon juice mixture and write a message on the paper by holding it over a lamp with the writing side down and see what happens. The invisible ink writing will slowly turn brown and appear on the page.
