What You Need:
- Paintbrush or toothpick
- Lemon, orange or apple juice
- Table lamp or clothes iron
You can write secret messages using fruit!
- Dip your paintbrush or toothpick into lemon, orange, or apple juice and write your message on a sheet of paper.
- As the liquid dries, it will disappear.
- Give your message to a friend and have her warm the paper with an iron or hold it close to a warm lightbulb and your writing will magically appear!
- Use caution while warming the paper.
This will not work over CFL or LED light bulbs that do not emit heat.
