How to Make an Invisible Ink Message
Posted by Aditya on June 26th, 2010
Have you ever wanted to send a secret note to a friend/lover where nobody can find it? Here is a funny idea but greatly possible to send an invisible message.
- Cotton Bud
- White Paper
- Pour milk into a bowl
- Use Cotton Bud to dip it into the bowl of milk. A toothpick, fountain pen, paintbrush are the alternative writing implements.
- Write your secret message on the paper.
- Let it dry! Give it at least 30 minutes.
- To reveal the message, you can iron your paper. The milk starts to burn faster than the paper and turns the secret message into brown color. The fat in the milk turns brown color.
