Science for Toddler: Magic Ink (Spy Version)
The Making of Invisible Ink~
Invisible ink has fascinated toddler for generations *yay*
You might think that it would be difficult to make, but it’s not 😉
Note: This simple experiment is great for young toddler, but must be conducted with adult supervision because it involves using the kitchen stove or candle.
Materials You’ll Need:
- some vinegar (you also can try this experiment with other liquids, such as orange juice, lemon juice, apple juice, onion juice and milk)
- some white paper
- a clean paintbrush (clean cotton swab or a toothpick)
- kitchen stove (or candle)
Step by step guide:
- Step 1: Mission In Action
Ask your toddler to pretend that they’re a spy on a secret mission, writing messages that would lead to big, big trouble if they were discovered.
Make them choose their words carefully.
*for this mission, I asked my kiddies to write their secret message to PaPa*

- Step 2: Start It On!
Guide your toddler to use the brush or cotton swab and write their message with vinegar on the paper.
Don’t use a lot of vinegar and soak the paper. Use just enough to make a thin coating.
- Step 3: Finish Line
After finished writing, ask the person whom is a special agent *in our case, Papa is the one!* to receive the paper and help them to turn on the kitchen stove to a low heat.
Very carefully hold the paper about a foot above the warm burner.
If you don’t see results, you may have to make the burner a little hotter.
Do not, however, hold the paper low over the burner.

Result: As the paper heats up, your toddler’s message will become brown and they’ll be able to see what was written.
You want to know why? (explain to your toddler):
Lemon juice and vinegar are mildly acidic, and acid weakens paper. The acid remains in the paper even after the juice or vinegar dries.
When the paper is held near a hot light bulb the treated portions of the paper burn, and turn brown, more readily than the untreated portions.
Have fun mommies!
Just be sure to follow all safety rules 😉
May all the best to you. Amin~
