Writing Your Lemon Juice Secret Message:
The process is remarkably straightforward:

Troubleshooting Your Secret Code:
Perfecting the art of secret writing requires finesse. Address common issues with these simple fixes:
-
Moderation is Key: To prevent bumpy, noticeable messages, use less invisible ink during the writing phase.
-
Camouflage Technique: Enhance secrecy by adding additional lines of ink around your message, creating a camouflage effect that only reveals the true message when exposed to heat.
-
Crumple for Concealment: If the dried message is too conspicuous, add a playful twist by crumpling the paper. The distressed texture adds an extra layer of concealment.
The Science Behind the Secret Message:
Understanding the science amplifies the excitement:
- Citric Acid Magic: Lemon juice's citric acid keeps the message initially colorless. The application of heat breaks down the citric acid bonds, releasing carbon that oxidizes in the air, turning the message brown.
