In this tutorial, we learn how to make invisible ink from an egg. First, grab an egg and poke it with a pen to where a small hole is in it. once you've done this, leak the white inside of the egg into a clear bowl. Now you can dip the pen into the clear liquid and write on a piece of paper. Keep dipping in liquid as the "ink" dries out. Once the liquid has dried, you will be able to see what is written on the paper clearly! You can place the paper or an open flame (standing back a few inches) and the writing will turn brown so you can see what you wrote!
