Secret Messages





Today we continued with our "Kitchen Chemistry" unit. We learnt how to write secret messages using lemon juice and milk and heat.  Seth wrote a secret message with kiwi fruit. When we added heat the messages turned brown. I wonder what else we could use?

My name came out very clearly. If you want your name to come out clearly you need to put lots of lemon juice on your paper. In the war they used their spit to wright secret messages to the rest of their army.
