Spy Writing

What if we could pass along information that can’t be stolen or intercepted? We can do it with a little coding, and some chemistry! Soon we will be writing in code, passing secret information along, and making sure it’s safe by making it invisible! Students will create two solutions to make disappearing ink, and a reappearing agent! Students will then encode words, make them invisible, pass them to a friend, make them visible again, then decode them! It's a lot of work, but also a lot of fun!
