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~

mamafiza the mastermind,

I’ll surely use this experiment with my kids. Hmm.. a good reason to use the ‘cuka’ in my kitchen.

After that, we can play the ‘I Spy’ game… I spy with my beautiful blue eyes (ekekeke) something that begins with the letter ’s”
hah teka teka..
