Hiding a message on paper can be a fun and simple project using common household items. One effective way involves creating "invisible ink" that only becomes visible when a developer is applied.
Using Baking Soda and Grape Juice
A classic method for creating a hidden message relies on a chemical reaction between an alkaline substance (like baking soda) and an acidic substance (like grape juice). The message is written with the baking soda solution, which is invisible when dry, and then revealed by applying grape juice.
Materials You'll Need
To hide your message using this method, gather the following items:
| Material | Purpose |
|---|---|
| Baking soda | Invisible Ink |
| Water | Solvent |
| An ink pen | Writing Tool |
| Paper | Writing Surface |
| Grape juice concentrate | Developer |
| Clean paintbrush | Applicator |
Step-by-Step Guide
Follow these steps to create your hidden message:
- Mix together baking soda and water.
- Dip your ink pen into the mixture, then write your message on your paper.
- Wait until the ink is dry. The message should be invisible or very faint.
- Use a clean paintbrush to cover the entire paper with grape juice concentrate.
- As the grape juice interacts with the dried baking soda mixture, your hidden message will become visible.
Once dry again, your secret message is ready to be sent or stored! The grape juice acts as the key to revealing the hidden text.
